Yes, it would. That you are asking this question makes us wonder if you would be better advised to contract with a independent FA laboratory to help you baseline your analysis. Among the fine labs to consider are: * Robisan Laboratory 6502 East 21

We've had much trouble with flex circuits. As previously mentioned, you must have local fids for the board or the BGA itself (if panelized). Other troubles we experience are drilled holes for pinned connectors. Unless the PCB manufactur has some w

I�ve been lurking on the forum for a while so I will take a stab at this, mainly because there is no answer I take it that you have a variety of boards being produced at the same time and are in fixtures so the conveyors don�t need to be adjusted, a

Hi, I have noticed we are getting residue on our wave pcb's and it's worse with lead free, since we changed to the flux we are using. We are currently using Avantec VOC Free flux model Ecofree 303. It looks like it's made in Malaysia. Does anyone h

We have fought with cut-tape way too much. It's always a bad idea. We've tried a couple methods/devices for manual splice with limited success. Before you look into this I would ask them if they could supply you cut tape qty's inslusive of fairly

If you have time, download the free Practical Guide to Understanding the Scope of the WEEE and RoHS, you will find what they say about UPS. They consider UPS out from the field of application of RoHS. ORGALIME (Bruxelles)is the European Engineering
