| I am looking for the Industry standards on vias. Are they required to be plated with solder or is copper plating enough? What about reliabilty with either one? Also, if tenting the via is required should it be copper plated or solder plated over

I am looking for standards that describe acceptance criteria for PCB's. Anyone.....anyone.....Buhler. My company is an OEM manufacturer and I want to know what to look for when we receive PCB's from our PCB fab vendor. Specifically, solderability an

| Is there an industry standard in calculating SMT process | PPM level for benchmarking purpose ? What are the industry | benchmark ppm number for some of the defects like solder | short for 20-mil QFP, tomstone problem for 0603 components etc....

Any acceptance criteria for hot bar soldering finishing? e.g. IPC-A-610? or anything else?

So, as I understand it, IPC6012 are performance criteria that your board shop should be using. I think you'd want to be using IPC600 for acceptance criteria at incoming inspection. At least, that's what I always did in my CM days. And, since you'r

| I work QA at an OEM in Alberta, Canada. I saw earlier posts on the smtnet regarding PCB haloing criteria. I am currently in a dispute with my PCB vendor over the acceptability of haloing (delamination) around plated through holes and vias on a lot

Hi Guys, (Note: We are not talking about bill-board RES/CAP, we are talking about Z-axis slant/tilted RES/CAP with respect to the PCB pad Z-axis plane). 1) We ref through the IPC-A-610C specification "bible", and can not find a "chapter/verse" tha

Good fillet at the heel is most critical. Check out IPC standards for acceptable solder joints.

Hi Russ, Thanks for the input. We already check our subcontractor mounting of the connector on the board and it seems that the problem is related to some batch of connectors from their vendor. Anyway, i believe that your suggestions on the agreement

As stated by others you are out of IPC compliance, However, There are allowable deviations to the standard as long as the purchaser and manufacturer come to agreement that the non-conformance will not affect form fit or function. I would recommend
IPC is the trade association for the printed wiring board and electronics assembly industries.
