One of our customers that always was going for Ni/Au surface finish on RoHS PCB and our processs was adjusted for that, "whithout any problem". Recently they decided to switch to another surface finsh: PbFree HASL. What is that? Imersion tin/silver?

Edmund, I agree with Wolfgang there is no reason for 0603s to be falling from the bottom side during the top side reflow. I assume what you are having problems with is a higher mass component like a large tantalum, inductor, or perhaps an active de

Jon, I believe were at a point now that all the problems related to the RoHS directive (not lead free only) are so abundant that they no longer can stay hidden. Here�s an article form the Swedish EIF http://www.evertiq.com/news/read.do?news=11736&c

We do the following things: 1.) RoHS PCB:s is marked with a code. This is to identify that the PCB:s itself are RoHS compliant. 2.) If it is a true RoHS PCBA; we put a printed label with a green "texture" on the PCBA. 3.) If it is a mixed PB free/PB;

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

Sorry this is such a long thread but I would like as much input as possible to everything I ramble on about... :) ------------------------------------------------------ We are now seeing more and more RoHS parts showing up in our SMT inventory and

From what I have seen some component terminal finished have a problem due to storage also. I have seen pure nickel finished turn black. I have seen silver barring finished have problems too. It all depends on how you chose your process, PCB plating,

Oh I agree with you 100%. I have been lucky and have not had to go RoHS...... yet. I can imagine all the hidden pitfalls and problems that could occur. But I guess that's were solid engineering pays off. Some people call it "knob twisting" but mo

I concern about the Through Hole soldering as well. Currently, we have encountered some problems of Multilayer from Through Hole soldering. The root-cause is probably related to PCB Finish, machine setting, Thermal relief Pad or hole and something e

Hi all, We produced a RoHS (lead-free) prototype order recently, and there was some components that we needed to replace on a couple of PCBA's. We found it very hard to do this even with the new solder iron. The components was just small RoHS SOIC's
