We had a similar issue with one of our products and ended up redesigning the whole PCB to fit the new parts. It may be little more costly up front than your solution, but should should have a much lower impact on quality and process and cost much le

Selective soldering machines are a good way to "finish automation", if the design of the PCB is conducive to the application with just a few components to solder. Your points are good. A decision matrix for selecting a machine might also include:

Hi Jeff, Your board supplier could be correct in this way. The board could have had just a hair left of copper on the circuit, which would hold up under the electrical test process, but once you powered it up, then there was enough juice to burn th

| Joni: What is it about your situation with the board/component/process that makes you want to explore alternatives? Dave F Dave: In our case the component is placed on metalled footprint which has via holes to transfer the heat via holes to the

All of our new board quotes include a charge for programming that's based on the component quantity and mix of SMT vs. TH. It doesn't take into consideration what it takes to reconcile BOM vs. PCB data inconsistencies, so we eat the cost of resolving

Earl, We have found that many people get closer to a zero defect program using pallets. Since you eliminate manula masking you eliminate on huge area of possible defects production. Since the pallets can align connectors etc, you get less defects due

One common practice, depending on what is on the other side of the PCB and how much heat you need to draw away from the part, is to manufacture a pseudo-heatsink into the board itself. It looks like a large tinned pad but has a dense array of vias f
