Thank you all for your replies. I guess my age in this industry is showing. This military spec. does not appear to be in existance. So, let me make my request a little more to the point: Is anyone aware of a specification specifically referencing

Hi, We are using mixed technology in our PCBA. Would like to know whether there is any criteria governing/guiding the use of mixed technology in such aspects as: 1. Some SMDs cannot be used in some kind of PCB materials such as FR1? 2. Some SMDs are

| I am interested in seeing how some of you calculate machine utilisation. Currently this was calculated off against the uptime. I really believe there is a better way of doing it i.e if I were to calculate this against machine's capacities. Any feed

Hi all. I have some experiance in regular electronics, but the hardest part for me was always the soldering, so I am very intrested in SMT. So what would be the best way to get started in SMT? I would prefer not to have to spend alot of money, but

I recently had the opportunity to visit the vendor who is making my boards. On my trip I noticed that the guy who was in charge of the SMD placement machine (brand new Samsung) still had to manuallly place about 20%-40% of the parts after placement b

| | Our first article inspection after machine placement can take several hours depending on the complexity of the board. The operator visually checks the board against the drawing and bill of material. I'd be interested to hear if there are any othe

Hopefully, everybody suffers from solderability of SOT-23 devices and I would like to know how everybody else resolves this problem. Historically, here, we have always gone for 6 thou stencils. I found that going to an 8 thou stencil improved the sit

I have an adhesive dispenser in my workcenter but I rarely use it. I've replaced this process with wavesolder pallets for bottom side PTH soldering, ocassionally gluing parts left exposed by the pallet. So I was thinking of selling the dispensing equ

Yes. We use high speed dispensing (PanasonicFA)as an integral part of our PCB assembly. Our business is automotive electronics and our typical product is 2-sided smd with some through hole. We assemble topside first, through hole, then bottomside. Th

I would like comments on how the industry handles 0402 parts, regarding identification. Since the parts are too small to be labeled, how can we accurately identify the parts and or values, either before or after assembly? When the boards go to test,
