Yes, providing your: * Inbound material does not compromise your process. * Soldering processes apply the proper amount of flux and activate it properly * Material handling does not contaminate your boards Recognize that the IPC requirements of less

We have using SAC305 type solder paste for lead free process. One sample paste received of SN100C.After reflow SN100C type paste joint looks brighter and good compare to SAC305. Please help me which paste is good for smt process?

Both SN100C and SAC305 are excellent and tested LF alloy formulations that with proper process management will produce good looking and reliable solder connections. "Bright & shiny" solder connections is NOT a good measure of a properly soldered LF c

Hi, I'm trying to implement SMED metric at SMT area in order to improve our change over (CO) up to 10min in high mix low volume process, ant at this moment the start and end point is the inspection before the oven, and what I'm trying to figure out i

SMT fine pitch connector having oxidation on lead and P&P machine keep rejecting the part. Is there any alternative way to reduce the part throw out rate without jeopardize the placement accuracy? Or is it possible to re-coat the connector lead or an

Hi Joe, first of all thanks for your input. I did tried to search for the Mydata brochure and found that they are using Lifescan Vision System (LVS) which i think should be vision analysis. Appreciate if you can explain more in detail how's the mecha

Your firmware is so old that the problem is not in the mod codes anyways. You have a problem with the cyberoptics head. If its not working at all, i would remove the lens assy on the front side where the cable plugs in and blow out the unit. Maybe if

Protect the board: If solder mask protects the board, the level of protection is limited and inconsistent. If you want protection, you need the be thinking conformal coating. Selective ENIG: I believe the reason solderability protection, except mayb

I wish I knew the MSL. The factory data sheet from 1995 does not list the specification. The moisture problem makes perfect sense for what I'm seeing. When we replace these parts by hand (no reflow) the failure rate goes down to almost non-exist
