content: Hello @llI'm trying to revive this board and checking here if anyone would be interested to have a bare board or an assembled onefeedback's etc ...I have designed and routed a new schematic revision ... i'm in process of ordering 5 prototype boards and checking for errors if any.In Canada I can have all the parts at Digikey for around 120$ Can for assembling 2 or 3 boards, and 30$ Can for 5 bare boards. Few years ago this board was sold for 900 EuroI'm waiting for an answer from a EEVblog member, if he would be kind enough to ship me his board to help me counter check my version, maybe send his rs232 adapter option too, to copy / dump the firmware and make it available.I'm not trying to take huge profit, but enough to cover material and parts, and add the missing options for my LCR Meter.I work in a pcb assembly company, i have access to smt assembly machine and solder posts ...

content: I will be sending a RS232 board and a DC board to coromonadalix by airmail next week, for reverse engineering, to get this project going.May be I can take some pictures before I send them out.

content: @ bravo similar look but not identical, since i will use dual op27 amp (opa2227) instead of single ones, reduced parts count, the change made a 25$ less in parts, the size is now good, it should fit ?Here's a look of the pcb 2-3 posts down this oneI have used radial decoupling capacitors for the moment, to help the second layer, the layer thickness or width size may be too small in the power lines. And I'm limited to 2 layers unless i pay more ... it double the price for a 4 layers 1 oz pcb'sIF high voltage send me his boards, i will compare them before producing ... i have only 3 missing supply traces from the SM for a chip, i could put them and cut them if needed ??I would like to build a potential list of buyers ?? for around 150$ CAD each, the chips are the one who cost a lot,The 1% smt resistors are around 0.35$/each for 36 parts count, and the resistor network chip is around 8$I used smt 1210 size to have possibility of the originals mma0204 series resistors ?? i'm not able to have all the values here in 1%.The strange thing with the res network is some kind of thermal coupling between the 8 resistors, they are in serial (4x1k) with an common point, i can't see another functionality than this, instead of 2 single axial resistors of 4k thermally glued togetherLIST:#1 is @bravo

content: GreatBtw, you can upload that file or any other supported types as an attachment as this forum, just look below the dialog box you're typing, it will be much better than external hosting, especially the free ones, just a suggestion.

content: Here's the final version ?? still checking if all is right before ordering, added some pads in RN111 for thru hole resistors ...In the service manual, there was some thru hole added parts in figure 31, the green board picture we see has the revisions integrated on the board.For the four thru hole parts, 1 inductance and 3 resistors i have to wait for highvoltage to ship me his boardand correct them laterIt should be ok like this too and still be functional.

content: It is a nightmare to find the original mma0204 resistors, Newark ask a minimum of 3000 parts to buy for 3 values total of 9000 resistors total of 380$ outchIn smt1210 sizes, i miss only a value of 4.64 megs, 6-8 weeks of delayI never tought it would be this difficult to have precision parts ... the boards are ready to be orderedSince the pm6304 and 6306 inside photos are shown, i'm sure the board will fit, they are identically positioned, and the clearance will be ok, not totally sure of the 6303 model .. my boards are almost 1 cm too high, the width is ok.Tried to shrink further the board, but the software has begun to take too much time to place and manage the parts (clearance, track width, parts spacing etc..), i helped it by taking thru holes decoupling 0.1uf capacitors instead of the smt ones.I can only make 2 sided boards, if i do a 4 layer one, the costs are jumping up really fast.

content: I stopped this project, parts are still available if someone wants them ( negotiable ) , costed me 130$ Cad, ( cant recall, but maybe enough parts for 2 boards or more minus the relays, (have only 2 of them) not the same foot print for the resistors, i could make a board the same size has the original one, but moved on to another stuffThe biggest problems was to find the same precision resistors parts, here in Canada, i did not have many choices.I dont have the pm6304 lcr meter anymore ... i have an Sencore Lc102 instead.No pcb's where done,managed to output a gerber fileHighvoltage was kind enough to send / lend me an original board of his 6306 lcr meter, had put countless hours to patch and fit the parts, it was my first attempt to make a board design.It was made with easyeda, im having a hard time to work with this interface. The board routing was a nightmare, it would not place the parts correctly at the tiimeRemove all .txt extensionsChanged the First thread title, project stopped.

content: That is good to know. I have a PM6304 incoming with a unclear situation regarding the option boards. While it has been stated that the unit is capable of DC measurements, this might well be a excerpt from the manual instead of the actual fit. Depending on what I will find, I might contact you for what you can offer.Knowing that the Gerber file would be available is the major part.

content: In the previous posts i've put the gerber files, easyeda has a partnership with jlcpcb I think the boards should cost around 2-3 $ a piece ?? its only a dual layer board.The pm9565 board costed way more than that at the time loll i've read 250$ usd ??Normally its the 6306 who has this board by default, not the 6304, it was an orderable option.

content: As the last post from this thread, i've removed all the files and pictures, i'm definitely moving away from this projectI have the parts for 1 board and some left overs for a second oneIncluded is the scanned part list from Digikey in 2017The last schematic and gerber files re-generated in 2021Still have theses parts in un-opened bags, price cut in half / make me an offer if someone is interested
