What trays are made of? It depends. Look here: http://focus.ti.com/download/qlty/esh/Shipping_Tray_Product_Content.doc There no IPC standard for trays, but look here: http://www.esda.org/documents/S541FINAL-04-09-03.pdf ... and the reason you

My thoughts on metal trays: One problem with a metal tray relating to ESD is its conductivity. Most trays are conductive but have resistance or a disipative nature. If you were to place a "charged" component into a metal tray that had an uncontrol

We seemed to replace a lot of optical couplers and absolutely hated that the calibration instuctions in the manual were not translated from German. [Got politely escorted from the Novastar Booth at a trade show for complaining to the company preside

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

It appears that this particular PCB supplier has a non-optimum HASL process along with other issues. It is much harder to completely remove the solder out of vias on thicker boards. Looks like more air pressure was needed to remove all of the exces

It appears your board house is having a problem with the solder resist (mask). From the couple pix it appear that the holes are being plugged by the mask, so your HASL is not able to be blown out during the hot knife process. Time to call your boar

Normally, you should not have to bake boards that are properly packaged and stored. Since you are seeing problems, baking makes sense. Consider 125C for 4 to 6 hours. Additionally, look here for more, while waiting for others: http://www.smtnet.

Does anyone know whether it's possible, given a copy of OS/2 Warp 4, and the Universal software, to set up a standalone box, not connected to the machine itself, in order to do programming, etc, faster? I've got the feeling it is, but I'd hate to in
