Hello, in my SMT process I have some problems with the solderability (look like dewetting) on a PCB with finish HASL Lead Free with a composition that is melt at 230 degree Celsius. My oven is with vapor phase and the peak temperature is 230 degre

You're creating a new alloy on the surface of your board. The alloy will have a melting point determined by the constituent metals of the alloy. Your alloy consists of: * Lead-free HASL solderability protection on the board * Lead-free solder paste *

Hi, everyone knows that we will soon phase into Lead free process.would it neccessary to waste so much money for such a lead content monitor? Bryan

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

In general two step temperature reflow process requires minimum 40 deg C delta to be sucessful. We are not using vapor phase soldering but we have similar situation when we change to SAC lead free solder for PCB component population and secondary swe

I am in the mid-Atlantic US. I need to solder PCB's to a large copper heatsink. Does anyone know of local (or not so local) ECM's with vapor phase capabilities? How about induction? Thanks!

Machinebuilder, We have Vapor phase ovens in our facility. We are located in OHIO. Let me know if you need more information. Thanks John
