It is true that the SAC alloys are very aggressive to unprotected solder pots but the SN100C lead free alloy can be used in these pots IF they are not already being wetted by your SN63 alloy. FCT Assembly offers a program that includes free tin wash

We have 2 dual head Versa-flows in line. We use them mainly for doublesided reflow jobs that have connectors and axial parts. I have about 15 jobs currently running on them. The advantage of having 2, is some of our boards have through hole on 1 side

We have a dual pot machine. The fluxer is not the slowest part of the process on most boards. However, we looked at running boards that had many hundreds of TH leads that we currently run through the wave in order to try not to buy a wave for lead-fr

Hello, Could anyone provide some support concern issue with vertical fill of through hole solder. Our lead free wave soldering process is not capable to fill 100% (requirement of our customer)through hole. We made everything (DoE) - different amoun

We are currently wave soldering connectors that are held in place by stainless steel screws. About 20% of these screws emerge from the process with varying quantities of solder attached to them. We have just had our solder bath checked and no impurit

6 deg is std angle. Some machines have option to adjust angle from 5 to 7. Maybe yours does. If you have an Electrovert wave machine you can get the Omega option. This option vibrates the wave to reduce surface tension. It does a nice job on rectangu

Not sure about Sn/Cu/Ni large market share here in Europe as we have a large part of the UK market with SACP0307 alloy 0.3%Ag introduced over Two years ago Also worked against Sn/Cu/Ni alloy with large TV Co and they went with 0.3%Ag due to reliabili

We have used the SN100C for over a year now with fanastic results. We use the SAC305 for SMT and SN100C wire exclusively. There are no problem mixing the alloys. I am also on the commitee for the NASA testing. The SN100C did out perform SAC and SnPb

We tested SAC305 in our selective solder machine and found the dross production made it an unnaceptable choice of alloy. Personaly, I cant imagine dross in a joint being a good thing but if it is a very small amount and does not occur very often, y

Do not believe every thing your suppliers tell you, even a written cert does not guaranty compliance. We recently purchased a Niton XRF analyzer. The first day in use we found component�s that were made for us "RoHS" that were far from compliant. Peo
