GR@ICS, can you be more specific about your up in the Ersa machine please? Nozzle size, pump rate (%), and is your machine equipped with monitors on the solder pots? We have the same machine it sounds like, however we run Pb-Free in both pots. I

I will second the recommendation for Count On Tools. I've shipped sample parts out to them next day air (let's say on Monday), Tuesday they received the parts, made the nozzle, and shipped it back for Wednesday delivery. That is not normal turn tim

Never did find a fool proof solution. Solderability seemed O.K. (at least using the methods we have available in house). Tinned parts and placed by hand and saw little improvement. Pad design is slightly different than recommended but likely not i

I have made couple of investigations with our oven. I set-up 5 product profiles and run a thermal profile measurement and record them. Then I set-up one more product profile and rename that as Validation Profile then measured the thermal profile. A

Tolerance stack up has really become an interesting issue with boards coming from China. What has usually been taken for granted has to be looked into with a fine tooth comb. Most board houses of the past would reject this - but China figures "If i

Thanks for your replies. The problems do not appear on the complete lot of PCB's. I don't know the percentage at this point. I agree. It also appears to me that these PCB's are over-etched. The PCB rep say's "Yea, there's a few boards that have
