0402 wave soldering

Hi Andrzej, I guess you mean peelable solder resist. Good idea to try during R&D, but certainly not a solution on production floor. Also, few constraints to be considered such as presence of entrapped air between component and solder resist, the natu

Hi, If you don't have a space constraint, why not check out the XPF machine. We just got the second XPF-W machine in the world to ship, and it's amazing. Huge boards, and the same feeders as NXT. Auto backup pin, feeder change on the front of the ma

Hi Norah, Thanks.. Components are stored in controlled environment of 20 to 25 deg c & 40 to 60 % humidity. Baking wont be feasible for many parts. Mainly for passive parts in tape and reel. 0402, 0603 & 0805 packages. Cold baking is not feasible

50% of cost, bin it. If viable, spend no more than that time to fix. Then concess or use as is. 3) Components are more tricky. Can they be returned to supplier if deemed to be faulty? (proof?). Is/was there an in-house handling problem ? Have design
