content: A few months ago, there was a discussion here where the source of the 3M boards was discovered.http://www.assemblyspecialist.com/WebStore/TSandDS.htmlThey ship to the USA, but not over seas. so I guess you're lucky @goethertAsh.EDIT: When I said source, I meant manufacture. I talked to the owner there about overseas shipping and he confirmed they OEM to 3M.

content: Quote from: wilfred on August 21, 2017, 11:15:52 amGiven that Assembly Specialists is a manufacturer, not a distributor, and that their website goes into their manufacturing capabilities and equipment, it's reasonable to deduce that they don't outsource; they're a company others outsourceto. So yes, I expect that they're made in USA, and I think the product may say so, though I don't have it in front of me to check.Cheap breadboards have contacts made of cheap metal that deforms easily, losing grip force over time. And that force isn't that great to begin with. This leads to poor holding of components, high contact resistance, and low long term durability. The 3M/Assembly Specialist boards have high quality contacts with higher force don't lose their springiness, and the grip is much firmer period. The result is a dramatically more reliable connection with much lower contact resistance. (My worst cheap breadboard has contact resistance over an ohm, while the 3M one is just a few mOhms - and that's not the gold-plated version, whose resistance is probably lower still.) I also suspect that contact oxidation is a problem on cheap ones.Indeed, the higher grip force of the good breadboards can actually make it hard to insert cheap Chinese resistors with their hair-thin leads!!

content: Quote from: bd139 on August 21, 2017, 08:31:07 pmIf it was only 2 minutes to get adefinitively validanswer, I would agree. The problem with solderless breadboards is the capacitance (either too much or too little), inductance, and especially the highly variable contact resistance. The consequence is that you spend more time debugging the breadboard than the circuit - with the emphasis on "you", since I refuse to look at circuits on solderless breadboardsIf inductance doesn't matter, it is much better and more certain to tack components together with solder. If inductance and capacitance matter then it it better to use one of the several manhattan or dead/live bug techniques that give reliable permanent results up to VHF/UHF.

Otherwise, Wisher would likely be the best choice that won't cost you a first born child.

content: Quote from: floobydust on August 21, 2017, 07:55:05 pmI have been looking for one or two more breadboards and as part of the research I sent Global Specialties this question:What is the difference between breadboards PB-104 and PB-104E ? I have looked at the datasheets hosted by DIGIKEY, but cannot see a differenceThis is the answer from their tech support:I am contacting you this morning in regards to your question about the PB-104 and the PB-104E.The main difference is that the 'E' stands for economy. The PB-104 is a better quality with parts sourced only from the US, while the PB-104E has parts coming from Taiwan. Though we still stand behind the PB-104E and it does come with a three year warranty.FYI, these breadboards are 4x units over metal base, with 3060Tie Points, 9X8.25. The E goes for $50 and the better one for $70.I thought this was worth posting here.

content: They may not posses aMade In USAlabel, but they're confirmed to be US made.Regardless, they're top quality IME (3M labeled in my case), and arguably the best available from any manufacturer. Even vs. US made Global Specialties (i.e. PB104) when pushing the frequency limits (otherwise I couldn't tell). For disclosure, mine where manufactured in the mid to late '80's.But buying directly from ASP in the US at least is a no-brainer it seems IMHO (cheaper than an equivalent from Global Specialties non-Economy version, which are still purportedly US made). Suspect that this may also be the case in the UK/EU. Under the 3M label OTOH, ...Cost wise, it's nasty with a 3M label slapped on it either way.Worst case, I wouldn't go less than Taiwanese made Wisher (also decent stuff; bought a year or so ago from a RadioShack that was closing). Not gold plated though, so I'm not sure on long-term reliability vs. the gold plated ASP/3M I'm familiar with (IIRC, Global Specialties is nickel plated).-----------------------------All this said, I actually prefer to use inexpensive protoboards (i.e. dual sided PTH pad-per-hole + SMD IC break-out boards) and solder everything. Even if it's truly not the case, I do this as it makes me more confident in the electrical connections vs. solderless breadboards, especially if you're working above ~10MHz. FWIW, I find testing a filter is usually fine within the previously mentioned ~10Hz max frequency (i.e. quick & dirty method).Oh, and I can use this method using strictly SMD parts (i.e. 0805 works rather well on the dual sided PTH protoboards IME). Generally speaking, cheaper too.YMMV of course.

Heck, I'm not sure that they really wanna deal with the formalities of selling to individuals within USA: they've raised their prices since I first posted about them!

After a second email with GS I learned:"Unfortunately, due to costs, the 'premium' line of breadboards was discontinued. The warranty for all of our breadboards is 3 years."Bummer !On the positive side, Tequipment has a sale on the GS breadboards. With member discount:PB-104 $56.36 (regular $70)PB-10 $19.25 (regular $24.70)PB-60 $32.76 (regular $42)I was tempted to order one PB-104 and two PB-10s...Then I looked for small staple shaped jumpers. The 3M go for $20 a 200pc pack, which makes it impossible... Looking at the Assembly Specialists (makers of 3M breadboards) page, I found the same jumper packs for $5.25, which makes it worth for me. This made me change my mind and I ordered one pack each of sizes .2"-1" and some of their breadboards.

If the financial side isn't, then Wisher would probably be the best way to go for cost-performance.Don't recall the original prices of just the terminal strips, but the metal backed breadboards and jumper wires haven't changed since the last time I checked.

Just make it and ship in volume to 3M for the most part (some direct sales on the side, but without the marketing or sales staff).So it has some advantages.Schmitzfor example operates under the same model with their cutters and pliers (i.e. ODM for C.K.

content: Quote from: nanofrog on November 11, 2017, 02:48:01 pmNot a lot of people know this, but a lot of major brands resell their products at much lower prices under no-name brands.If you sell to the high end market you find that the price is much more elastic with a high offset. People are prepared to pay MORE than it's actually worth to get guaranteed (perceived in a lot of cases) quality.In doing so you price yourself well out of the budget market however. Nobody in that market wants to pay premium prices for "it'll do" quality goods.That's a big market though. Shame to throw that away. So they rebrand their goods to an unknown brand name (and even change the name frequently) and sell them at a much lower, but not zero, profit margin; it's still gross profit. It has an added bonus of squeezing the up rising budget brands' margins to defend their higher end brand.Bridgestone tyres are current Lassa tyres in the UK, for example *or so I'm told*. A bridgestone might cost you £100 a corner but a Lassa might cost £50. Still the same tyre, possibly a B grade bridgestone at worst.I wonder if the likes of Fluke or Aiglent brands do similar.

Ive got a couple of them and I find them to be not so bad really, certainly a lot cheaper than the 3M units. I also have a couple of individual breadboards that I bought as a bulk lot from Elegoo on Amazon - biggest pieces of sh*t Ive ever come across, do not recommend (they dont grip well/feel very loose and I think sometimes that resulted in intermittent contact, and the alignment of the metal parts is so bad that sometimes it is near on impossible to insert a component lead in to a hole)Dave has some K&Hs too it would seem, seen them floating around in some of his videos.One word of caution with the K&H's, some of them dont have power rails down the sides like you might expect, which can make it a bit more painful to work with especially if youre doing a lot of digital stuff and need lots of connections to the power rails for pull ups/downs etc.

content: Yes this is true.At this point I am working mostly with SMD parts so I spend most of my time either making up simple boards (etch resist pen+ fr4 stock) or getting them made.I use the 3M board mainly for quick bias network tests or hooking up a programmer to an MCU or something.I still think they have value for learning though even with the limitations on reliability and lifespan. The better boards are useable. Just don’t expect them to last forever and don’t fight them when they are circling the drain

Normal price is $4.95 or 3.95 if you buy 10, however a few times a year they put them on sale for $2.95. I can find no brand name or markings on them, but i have seen a video by Ben Eater on the construction of the boards he uses. He has a checklist of half a dozen points to look for and these boards pass them all. Worth trying a couple and if you like them, wait for the sale and stock up.http://www.mpja.com/830-Tie-Point-Solderless-Breadboard-Unmounted/productinfo/24443+TE/

content: Just to let you know, I ordered two small breadboards from Assembly Specialists (ASP) for $100 based on this post. However, the ASP breadboards turned out to be extremely difficult to insert wires into, and even the jumpers provided with the boards tend to bend if you're not careful. The ASP breadboards won't accept the male pin headers on my breakout boards, which is what I usually work with. In comparison, the old breadboards I have from Radio Shack or surplus stores are much more accommodating. I know new breadboards can be stiff, but these are way beyond.Are the 3Com boards just as stiff?

I have two of the Radio Shack boards from the 1980s. They were almost certainly relabels of 3M/AP Products. The fit on those is not quite as tight as a newer 3M.

content: Quote from: rdagger on March 06, 2023, 02:28:49 amYeah, it’s normal for them to be very stiff when brand new.I personally avoid using standard male headers on breadboards simply because they’re at the very upper limit of the allowed wire thickness. But if you choose to use them, just insert a low-pin-count header into the holes you want to use, just to open them up. Only the first insertion is super tight.As for component leads: I suggest snipping them on the bias so they have a point. Makes a huge difference in ease.P.S. 3com hasn’t existed for 13 years. You mean 3M.

content: I found nice an tight breadboards. Cheap on Amazon.The problem I have is when you use a square pin header in a BB hole, the whole row seems to open. My usually breadboard to breadboard link of choice are the little steel pins with the rubber grip style. The later always seem to cause issues with poor connections.The issue is two fold I think. Partly the header pins are forcing open the entire row of metal clamps. Also partly the steel pins are no doubt subject to corrosion/oxidisation and being a pretty hard metal doesn't abrade easily (like copper or gold) so doesn't self clean being inserted/removed.I just can't keep complicated digital circuits running. Because I had power issues on a set of 2 large breadboards I had begun edging up the system voltage. Now instead of doing what sane people would do and power the breadboard with 5V and use LDOs and capacitors to supply the 3.3V, I ran the PSU on 3.3V. I found I only had 3.1V at the end of the project so I upped the voltage to 3.5V. This is fine, almost everything that takes 3.3V takes 3.5 or even 3.6 right?Well, it ended up with the PSU running at 3.70V. I found out the hard way, that no, not all things that take 3.3V take 3.7V and when working with bare modules with a 3v3 input, they mean 3v3! They have no regulator or limiter onboard. Lost an Optical I2S module last week and this week through similar impatience and stupidity a 2.4" TFT.I ordered the PCB for this particular project, but I'd love to not have to go through that again!Any suggestions? Do I abandon the steel pin jumper leads? Do I use only dupont? Do I just accept things are as they are and make more proto-board interconnects when the breadboard circuits become "more settled"?On DuPont. I find the females you get one connection. Maybe 2. Then they loosen up and don't make good connections. You can sometimes squeeze them with pliers and get another few goes, but often you just crush them. The males on the other hand, if they don't want to go into the breadboard and you push a little too hard, then buckle, bend in the middle and snap off.I seen a breadboard a long time ago, demo'ed on YouTube, where the "flutes" where individually cut between the holes, so that each individual hole could open the jaws as far as I needed without forcing open it's neighbours. I can bet 99% of the clone manufacturers just skip that step as it's expensive. They also probably use horrible cast alloys which oxidize and get filthy.If it worth givng the breadboard and all the jumpers a bath in iso or something?

content: Hi,I've used Radio Shack solderless plug boards and they were the best i had so far. They all get old though after a while.You can get the bottom off for cleaning and possibly rebending.For real professional work though i've always used a wood plank and stand offs and terminal strips. For heavy currents you cant use a solderless plugboard (breadboard) anyway.

The best in this regard is the Amphenol Mini-PV (PV being short for “perpetual virgin”, according to Amphenol, due to their high mating cycles). They’re rated for about 1000 mating cycles, thanks to a separate phosphor bronze leaf spring inside it. They also cost 10-20x as much per contact, but in the long run it saves money, not to mention nerves.I haven’t had much trouble with male DuPont pins. They should not give you any trouble even on a new, stiff 3M board. When I’ve had trouble inserting those, it turned out it was a remarkably shitty breadboard whose contacts didn’t have enough of a funnel, so inserting anything was nigh on impossible. If you do manage to bend a male DuPont, remember that it’s brass, so bending it back just a few times will cause it to snap.Upshot is, the cheap stuff ends up costing you more in the long run, and lots of time and stress.

content: Quote from: tggzzz on March 06, 2023, 11:50:01 amHmm. I've been muddling in my head over breadboard use.I think they are fine if you are plunking out a few components to get an idea for a circuit using discrete components. Like, for example, I am playing with very basic boost/buck and mosfets (again!), while the solderless BB doesn't afford a very good buck topology and won't even allow most buck ICs to function properly, it still works for learning the basics with the scope. With the scope attached it's very obvious when loose connections get involved.However, when circuits grow and that buck circuit now becomes a "stable part" of the large circuit, it's time to a) replace it with a module, b) move it to a soldered basis (dead/live bug, protoboard etc.). Things would at least be more reliable having 3 or 4 small sub circuits interconnected on the breadboard.That brings me to where I am with the projects which are torturing me. When you want to combine half a dozen modules. The modules might be a power supply, an MCU and 3 or 4 interface modules like DAC, ADC what not. Keeping these stable is a nightmare. At the same time the modules can become expensive. For example the optical board I cooked cost me £35. Not going to starve buying a few of those, but they take 3 weeks to deliver and could vanish from stock tomorrow. So, I whatever I choose to do, needs to be undoable and the modules easy to reuse if required.Jumping over whatever that technique turns out to be, I get to PCB, where I can get 5 boards. I can use the first one with female headers and plug modules in. When I'm happy I can just solder the modules directly into the board. It's just the turn around time and cost printing PCBs every few weeks is irriating.So, I'm thinking about buying 3mm plyboard. I already have plastic standoffs. I'm going to screw the modules down to the plywood and solder wires point to point between them, directly onto the dupont pin headers. These simple touch contact solders are instantly undoable with a touch with the soldering iron. The pin headers should be reusable, at worst they'll need a quick clean up with the iron. I can even use little bits of protoboard for things like voltage regulators and power distribution boards. I can solder decoupling caps to the power header pins directly etc. It should then remain far more stable and when it comes time to do that PCB 15 minutes should unsolder it, the same modules can go into the PCB, any mini-circuits I made, like a buck or power supply module, convert to PCB discretes.

content: Quote from: paulca on March 06, 2023, 12:26:31 pmIncremental design, implementation and testing is an important - arguably necessary - techinque, and one that demonstrates the problems with solderless PCBs.Hence I've shown an example inhttps://entertaininghacks.wordpress.com/2020/07/22/prototyping-circuits-easy-cheap-fast-reliable-techniques/about 2/3 the way down that page. With that kind of technique you can delay moving to PCBs until it isnecessary.When connecting modules made using any technique, do ensure the ground wiring between modules doesn't introduce problems; make sure you understand the consequences of a wire's 1nH/mm. and whyallapplication notes show and/or stress the importance of ground planes.Signal integrity with digital circuits is a real issue, whatever the clockfrequency/period; FFI understandhttps://entertaininghacks.wordpress.com/2018/05/08/digital-signal-integrity-and-bandwidth-signals-risetime-is-important-period-is-irrelevant/

Lots of quality products are made there.With that said I largely concur with your experience. I’ve been little by little remaking my female DuPont leads (like banana to DuPont, micrograbber to DuPont, DuPont to DuPont, etc) which were originally made with Chinese DuPont contacts, with real Mini-PV from Amphenol. Yeah, each contact costs 10-20x as much as the Chinese one, but it lasts about 300x longer without loosening.I also have been using more Molex KK, since they fit into single-row headers, and their spring design is more durable, even in cheap clones. (But even more so with phosphor bronze originals and clones.)What I have had very good luck with is Chinese silicone-insulted wire — at least with the supplier I’ve been using. They carry it in thin sizes the western vendors don’t sell, in more colors. So I’ve been using that to make my jumpers and test leads.I managed to stock up on 3M/Assembly Specialist breadboards bought direct from Assembly Specialist before they raised their prices, so I should be set for a long time.
