With recent implementation of VOC-Free flux in our shop, we've experienced little solder fines/balls on the above combo of VOC-Free, Water Based, and glossy to semi-glossy mask finish on PCB's. The solder balls show up on close conductor spacings, ~

If you want an inexpensive, good, somewhat dedicated, solution, then I would use a desktop wave pot like Wenesco or better yet Air Vac. The PCBRM10 or PCBRM12 from Air Vac may still be available. Can find on Ebay also. They have a quick change, pr

Yes you can use no-lead parts in a leaded process. Your solder joints will be weaker than they once were unless you change your solder paste. You can try to improve this by running a hotter reflow temp, but be careful since your flux was not design

With the costs of bar solder going through the roof manufacturers need to try to offset the dross related losses any way possible. Companies employ reclamation processes but in practice this only yields roughly 1/3 of the original cost of the solder

Micheal, What does your profile look like for the wave? What profile does your flux say you need? My guess is it is not your profile, our testing with solder balls found that the mask on the boards was the largest contributor to solder balls. Wha

Dear all, Referring comment from Mr. Jack,IPC director certification & assembly technology, the term "fillet tearing" is too broad. Cracks or fractures in the required fillet area, with SnPb or LF alloy and whether you call it tearing or not, is a D

Chapter 1 of Handbook of Machine Soldering: SMT and TH [Woodgate, RW; John Wiley & Sons, Inc.; 3e; 1996; ISBN 0-471-13904-1] is titled "A Brief Histroy of Machine Soldering". While a tantilizing title from the perspective of your project, it simply

Preheating is critical in Vapor Phase Soldering. One trick that is done is to use the "soft vapor" area just above the soldering vapor, some machines can pause just before going into the soldering vapor. Using that pause above the vapor to continue
