content: I use Altium 18.1.9My problem is that with a fresh document and default settings, some components (PINs) are not matched with the grid, it means no straight line can connect them. very annoying. I had not this problem with the older versions. I use default libraries.TheEdit -> Align To Griddoes not help.

content: Anyone can try this. create a new schematic document (everything default) and pick up a transistor from the default libraries. You can not align all pins to the grids at the same time!actually, this can be tested with any component that its pins are not straight aligned such as a resistor, a diode ...try headers, Potentiometer, mosfet, transistor and similar ...

content: Sounds like your component and schematic do not agree in terms of grid size/type. To get around this make sure that the grid units agree in both, as in both are at imperial or metric. Once you have that sorted make sure that pins are on that grid, as in you might have to move them around

I have the PSpice model of the following format.model IRF9610 PMOS(Level=3 Gamma=0 Delta=0 Eta=0 Theta=0 Kappa=0.2 Vmax=0 Xj=0+ Tox=100n Uo=300 Phi=.6 Rs=.721 Kp=10.37u W=.64 L=2u Vto=-3.814+ Rd=1.524 Rds=888.9K Cbd=222.3p Pb=.8 Mj=.5 Fc=.5 Cgso=1.517n+ Cgdo=30.29p Rg=2.4 Is=886.1E-18 N=4 Tt=1100n)2. I draw schematic of an amplifier based on 1 MOSFET and attach the model as .mdl3. During simulation couple of warnings appear like "unknown parameter Tox, Rs" etc.4. I create exact the same schematic in LTspice, attach Mosfet model as Spice directive. The result is ok, no warnings etc.5. I decided to export the netlist from AD to LTspice and the simulation result is NOK like in AD.What is the reason? Wrong syntax? How to properly export the netlist containing MOSFET model from AD to LtspiceI've attached the AD netlist and LTspice file.

content: Welcome to the wonderful* world of SPICE.No two simulators are the same. Many are derived from XSPICE, a free mixed-signal simulator base. They are differentiated by proprietary features: PSPICE support (PSPICE itself is popular enough that it's a defining feature of support by other simulators), various levels of models, digital code models, different solving methods and tweaks, etc.You may find this useful:https://techdocs.altium.com/display/AMSE/Metal+Oxide+Semiconductor+Field-Effect+Transistor+(MOSFET)+Modelthat said, TOX and RS are supported by Altium so I don't see why you got an error on it.Tim

content: It may be better to draw the paste mask manually in the footprint. Also, I don't think you want to have the paste mask open over the through-hole anyway, do you? I expect that would lead to poorly-controlled solder quantity (both because some will get squished down into the hole, and the paste in/over the hole will tend to get pushed out when the pin is inserted).

At the very least there's no basis to expect another AD17->18 level of update. Whether it's a net positive or not is another question, but hopefully AD18 gives them a better basis for improvement than prior versions.

content: they release a new AD major revision more or less every year for a long time.. as explained above, normally it's not that big a difference.. A new software component maybe, or some new features for existing components. For a while they were ever doing releases on season (AD summer 09, AD winter 09? which was bound to be great fun for anyone in the wrong hemisphere)Of course AD18 was a huge jump (similar to when they did AD10, and with a similar huge list of side effects and issues to iron out)AD19 will just be a continuation of what's happening with 18, maybe with a new feature somewhere.. probably will be mostly just more bugfixes, the way AD18 is going so far.

Everything worked in AD17 (most of the time), but with AD18, it randomly crashes in this state where I cannot even exit out.Just today, I was doing differential pair match routing. It kept snapping the box size back and it did not let me adjust the size of the humps (or whatever you call it). It worked after I deleted the interactive length tuning box and retried 10 more times.

content: In Altium, you make the changes in one place (usually the schematic), and then (D)esign->(U)pdate or (D)esign->(I)mport to synchronize between schematic and board.You can also enable Cross Select Mode (under tools) so that selecting a part in the schematic will select it in the PCB and vice versa. Note that in a multi-channel design you'll need to be in the compiled view, not the editor view (tabs at the bottom of the schematic window) in the schematic for selection to work properly.For all of this to work properly, you'll need to make sure your component links are accurate, under Project -> Component Links. Copying and pasting or inserting snippets can sometimes break component links, which will break all kinds of things, but it's usually fairly easy to fix.

Routing Width constrain by Component - Page 1

content: I'm struggling trying to build a routing width rules to a single component.Exemple: The resistor R1 has one pad on the NetClass "HighCurrent". There is a Routing Width rule for this NetClass to make the track 3mm wide.But for this particular resistor I want the track to have just 0.3mm. I tried to add a higher priority Width constrain scoping this resistor but it doesn't work.I tried: InComponent('R1'), HasCompParameterValue('Case Code','0805'), and a few other with no success.The altium seems to ignore component scoping on Routing Width rules... I think it just cares about rules scoping nets, netclasses and layers..Anyone confirm this and/or has any clue how can I do that?Cheers.Alex.

content: Tracks and polygons belong to nets, not to components, so I don't think there's a good way to do what you want. You can probably construct a rule for the track segment that is touching or within a certain distance of the pad in question, but it would be difficult to codify where Altium should stop applying that rule and start applying the other. You could use a room or a region to define an area where the narrower rule applies, but then you have a room or region you need to move around with that resistor, which is kind of silly.

I haven't used them myself but it may be what you're looking for.Otherwise, use a net bridge, positioned in the wide net, tapping off to a thinner net local to the net bridge and the resistor.

Altium and Decoupling Capacitors  - Page 1

timestamp: August 07, 2018, 03:51:56 pm
content: Hi --Relative Altium newbie here. I'm designing a PCB with an IC that is finicky about its decoupling capacitors (the lmx2594 frequency synthesizer IC). One pin wants 1uF, another pin wants 10uF in parallel with a 0.1uF, etc. Of course, these caps have to be physically close to the IC to do any good.When I transfer the schematic to the PCB, all the components are placed off to the side of the PCB with no indication of which decoupling cap belongs to which IC or to which pin. The decoupling capacitors just show up between Vcc and GND, which is topologically true but not what I want.In the schematic, is there a recommended way of specifying which decoupling caps should be close to which pin, such that the data will be communicated to the PCB layout? Currently, I put copious notes on the schematic but was looking for a better way. Couldn't find anything on this topic on the web. Thanks.Kevin

content: You could use net ties. These are special components that allow two nets to be electrically connected at a single point. So in the schematic you'd connect, say, pin Vdd1 and it's associated caps to an isolated net, and then use a net tie component to connect that net to your main Vdd net. The downside is that net tie components have to be explicitly placed on the PCB. Alternatively you could just use 0-ohm resistors, which have the benefit of being removable if you want to bodge in a filter or measure current or something on the test board.Personally, though, for situations like this I explicitly show which specific caps are connected to which pins on the schematic, then use Cross Select mode to grab the parts associated with each pin on the PCB by selecting them in the schematic, and simply move them to the appropriate location next to the IC. (And if you aren't already using it, Cross Select plus the Tools->Component Placement ->Arrange commands are really nice for quickly organizing parts on a PCB to reflect their logical grouping on the schematic sheet. Rooms can also be useful for organizing parts based on multisheet topologies, but they tend to be more annoying than helpful on small projects.)

content: I just use the Cross Select Mode option in the SCH to group components that belong to each other which works vice versa.the only problem would be is that if in the SCH those coupling cap's are drawn separate from the part it's suppose to go & that there are a couple of them in which you could just choose manually OR place them directly to the IC pin for Shift+Ctrl+X to work.

content: Hey all,I'm having an annoying problem that I don't recall ever having in AD17. Normally I go to place to part and when it's placed the designator shows R? or whatever as was specified in the library. In AD18, however, every part I'd place had an S? designator. Weird. I had imported my AD17 settings, so I went into Settings -> Schematic -> Defaults -> Part. Whenever I open this dialog, the part "Defaults" just show the parameters of whatever part I had selected last.Which...ok...that doesn't really make sense? So, OK, I clear the fields that were filled in with manufacturer information. The annoying part is the designator. I have no idea what to put in this field to make Altium just STOP replacing the designator specified in the library with whatever is in this default part field. How do I do that? I've tried leaving it blank, replacing it * or ?, and it doesn't matter. That just makes any part I place from a library have its designator replaced with exactly what's in that field. I.e. a blank results in a blank designator when I place parts.What am I missing here? Why is there even a default part setting to begin with, when this stuff comes from the library?Thanks for the help!

content: Remember IPC 'rules' are a guide. Nobody said they are perfect. Any value between the highest and lowest density will work fine...the larger you make it, the easier it is to get a good result. If you want to second guess the IPC rules, you can always use the datasheet for the particular device your working with and follow it's recommendation.For prototypes anything will work, for volume production, if you find a consistent problem with a particular footprint, it can be tweaked slightly for the next batch.

Board shops in China that can do wire-bondable Au - Page 1
Forum section: electronics / general

author: grouchobyte
author_rank: Regular Contributor
timestamp: August 18, 2018, 12:33:23 am
content: In recent years I have abandoned US and Canadian board shops because they have become un-godly expensive and refuse to accept the reality of Chinese board shops taking away their prototyping business. I have found that the chinese quality ( for straightforward designs) is exceptional and at about 10% of the cost compared with US shops. On the downside, communication can be a little frustrating, especially if you want to get something non-standard done.My current medical/dental equipment client has asked me to spin an optical front-end board with a InGaAs PIN diode at one end. The current PIN variant is in a can but the new design will have no can, so we are mounting the die right on the board(cathode-N) with conductive epoxy (eutectic in a later spin on for better CTE match) and the (anode-p) is going to be connected with a bondwire from the die edge to a single pad on the board. I specified soft wire-bondable Au (50-80 micro-inches) for only this one pad and our Chinese board house can/will not quote it. They only do ENIG plating.Having this done in China without the wire-bondable soft gold requirement would cost us $65 USD for 10 boards (including DHL shipping to the US). A US board shop would do it for $650 USD. Adding the soft gold requirement ramps the price up significantly, so again I am happy to tell them to pound sand and go offshore once again. If US shops think Trump tariffs are gonna save their domestic business, they are dreaming.To that end, I was wondering if any of you ( Blueskull?) can recommend board shops in China (mainland) that are reasonably priced and can do a decent job for a US-based customer. My wife is from Shanghai and she used to work in a PCB factory during the cultural revolution so language/communication shouldn't be an issue@grouchobyte

How to force altium to put connector on edge - Page 1

author: TheUnnamedNewbie
author_rank: Super Contributor
timestamp: July 23, 2018, 04:31:03 am
content: I'm making a design that uses a number of SMA edge launch connectors.Is there any way I can force altium to put the connector on the edge? How do I properly mark this in the footprint?

author: TheUnnamedNewbie
author_rank: Super Contributor
timestamp: July 23, 2018, 04:35:23 am
content: No, not really. I can place them manually on the edge, but I was wondering if there was some special feature to 'tell' altium it should be right on the board edge (and perhaps enforce rules when it is not). Rather in the interest of learning right now than a need since it is not too much work to do it by hand.

author: ajb
author_rank: Super Contributor
timestamp: July 23, 2018, 02:26:39 pm
content: I don't think there's any sort of facility for this really. You could maybe do something like place a line on a particular layer in the footprint that must line up with the edge of the board, and if there's a way to create a rule for a maximum distance between that might work, but I don't think there is.I would just put a reference line in the footprint that you can manually line up with the board edge. If you've got a bunch of connectors along the same edge you can carefully place one and then use some of the placement tools or even just copy and paste the X or Y coordinate (as appropriate) to get the others lined up.

author_rank: Frequent Contributor
timestamp: July 23, 2018, 02:40:14 pm
content: My preferred way to do this is to make sure that the footprint has its origin along the board edge. Drawings for many edge-launch connectors reference all dimensions to the board edge anyway so this is straightforward. Using a STEP model if available is a good backup to verify everything's in place. When dragging the part in the PCB editor, the cursor will line up with the origin and if you have snap to board edge enabled, the connector will snap into place.

content: Like AJB, I put a line on mech 1 (my nominal "board edge" layer) in the footprint design for things that need to be critically placed on the edge, and then it's pretty obvious if the part isn't placed correctly.Also works for PCB antennas when you want to make sure the antenna element will be always placed a certain distance from the edge of the board.

I need to create a top and bottom coverlay and a small stiffener under a surface mount connector.I have been unable able to create the top and bottom coverlay. What is the secret? I have one stack, the Layer Stack Manager is set for Custom and Advanced/Flex checked. Add layer has “Add Flex Coverlays” greyed out. If I uncheck the top and bottom Overylay (or delete them) I can do the add flex coverlay. When I do, those layers have silk screen text not cutouts for pads. What am I doing wrong? I also see no option for adding a stiffener.
