I am curious if everyone else is seeing the same dramatically reduced tip life with lead-free that I am? We have purchased new irones with controlled temperatures up to 800F. We are doing more hand soldering on our lead-free at the present while wait

Stuart, My suggestion is a DFM meeting (most of the process people dream about a meeting like this, and luckily, I've been to a few) with: - project manager (if there's one) - customer service rep (annual volume, lot size, product life) - smt proce

Hi Guru, I have a project to evaluate different kind of Solder Bar and Flux to be used in wave solder(RoSH)machine, to choose in which is the best to be use. What is your best practice to evaluate the Solder Bar and Flux ? Cheers, Setup Guy

We have a Ultra 2000 wave solder machine with a Lambda, Omega and Rotary chip waves. We are running three shift and our operators dedross the solder pot every 24 to 32 hours. That is skimming around the nozzles and pumps. Our maintenance does a compl

I think it is a good idea to "waste" money on this analysis. Especially if you phase in a SAC wave alloy. Silver is not toxicity free....and lead free waves can dross 3 to 5 times faster than SnPb alloys. This produces a greater potential for airb

Hi, All these guys have provided you good solid infos already! All I can say is that check your wave solder machine's mechanical set-up too...and the Molten Solder Level in the bath must be maintained at an accurate level/height specially after ded

A couple of things that have helped me with solder ball issues at wave in the past: 1. Flux. Insure good flux coverage on the bottom of the board. 2. Preheat. Insure that the board is sufficiently preheated for the wave operation. Since you're

Eric, We also have a UPK 650C. Our machine was configured for N2 and using the ConTour nozzle. If you're using this nozzle without N2 you're creating tons of dross unnecessarily not to mention probably getting tons of icicling. We found out the h
