To: Wave Master Larry, You are correct in one respect. There is always dross on the wave, but it is a result of oxidation of the tin and lead. It IN NO WAY POSITIVELY EFFECTS the solder process, in fact, dross trapped in the solder joint is a detri

Samir brings up a good point with convection ovens. The flow rate of the fans can move parts, which can cause tombstoning to very light/small components. Also, check you conveyor and or chain. If it is not running smoothly, even a slight shake o

We just installed 2 YESTech 2050's for our 2 lines and I'm extremely happy with them. Our machines are setup inline post reflow w/ the capability of diverting good/bad boards utilizing Nutek's t-type turn unit. Of course, we all know that the objec

Good day, Probably i mixed up the model numbers. Nevertheless, my own opinion obout Marantz AOI series will always remain negative due to facts mentioned above. P.S. I suspect that you are PetroInTrade sales representative. Am I right? BR, Pavel

Good afternoon, I saw Matantz AOI machine in work more than year ago, I forgot and mixed up model numbers. I�m sorry for this mistake. Probably that was smaller brother of M22XDL 460. Model I saw had real disadvantages mentioned above. Nevertheless,

Good day, Vibratory (MultiStick) feeder is bottleneck of any placement machine. If you feed expensive IC�s via vibratory feeder they surely will be damaged. If you really care about expensive IC�s equip you placement machine with reject conveyor. In

We use an alignment jig {from Fuji I believe} that checks any rotational offets from the shaft to the head. The bottom of the jig fits onto the head while the top slides around the top "what I call" the crown gear. I've had several instances where

Wow, these are still around? Don't go IR, especially with these units. They are very inconsistent. Maybe for adhesive, but I wouldn�t try reflow with them. Yes, you can reflow with them, but this model of oven will constantly change on you. I

I have used Winslow preforms several times.....sometimes with great results and others with not so good. It just depends on the BGA. I have a custom ASIC that will not re-ball, Winslow has even had trouble re-balling them. I would suggest using an

Hi all, I just wave soldered 40 boards (20 if Imm Sn and 20 of Imm Ag) using SAC 305 (in this case the wave machine manufacturer (electrovert) suggested the alloy too). plan to carry out x-sectioning to see the results. overall, just from the visual
