Hi What is the surface finish you have? Following are true if you have HASL-LeadFree surface. I have had the same problem 3years ago and we did some micro-sectioning for further analysis, still the boards are functioning properly. But you have to

Dear Sir. Recently we had a problem in our production. We had pcbs with no RoHs (with solder Pb in pads) but we used paste Lead Free. I want to know if we will have problems in this solders in the future, because (perhaps)the solder will be broken, o

Lead Free in 5 zones is tough sledding. Start with your manufacturers solder reflow profile and calculate your belt speed by looking at the recommended heating time for the solder paste vs. the length of your heated zones. Set your belt speed so tha

It depends on the laminate but a PWB is like any other MSL component. Some fab shops are only waranting standard FR4 laminates for 45-60 days when processed at lead free temperatures. The best thing I can say is to try some weight gain/loss experim

Doesn't the components and PCB need to be lead-free also to be a "true" lead-free process?

Sure, to be a true lead free enviroment all components need to be lead free or fall within the specifications of lead free as defined by the RoHS Directive. What I am doing is starting stage 1 of our journey. Layed out it looks some thing like this.

Hi Jay, Concerning you PCB, what TG do you expect to use for your lead free process? On my side I have a problem. I order PCB from Canada and from China. My PCB vendor in china is producing a lot of OSP and ENIG PCB, no HASL lead free and in Cana

I have two questions that maybe someone can answer? 1. Can or should lead free components be used with standard 63/37 processes? including sn/pb pcb's? 2. Can or should sn/pb components be used for lead free process? I have recieved mixed feeling
