From personal experience, I agree with Dave that pre-owned equipment is often a more favourable option than the OEM route...provided that the equipment is purchased from a reputable source, supported with some kind of warranty, and be aware that some

The diode doesn�t appear completely broken. It takes a bit white color (cristal break, I think), instead of the normal red/orange. It works like a 20K-200K ohm resistor. !The diode can be working properly and sometimes change to bad! I think it may

HJ: Your best chance of running your boards with a single profile is with ovens from the established suppliers (ie, BTU, Conceptronics, Heller, Vitronics, etc). They are experienced in robust control system designs. Stepping aside from that, consi

Mr. Kim: The answer to your question depends on the type of mix you are dealing with. Here is the approach you should be taking to answer to your question yourself: 1. Establish the reflow process specifications for products. 2. Profile your p

When switching from cleaning RMA to a no-clean flux, one area that is commonly overlooked is the stencil cleaning operation. Stencil cleaners that are effective in cleaning RMA often fail when cleaning no-clean (especially alcohol cleaners). Pallet

We are experiencing 2%+ dropout on one particular SOT23 device. This seems to occur during the actual pickup phase. I have made sure that my pickup position and height are correct. If I single step through the forward feed of the component, viewing i

This massage is for clarifications on storage and handling of Moisture sensitive parts: Does chip resistors,capacitors and inductors need vacuum packing during usage life? For repacking of FPDs to limit reuse, is it necessary to use vacuum seler or s

If at all possible avoid mirror assembly BGA designs. It has a higher failure rate when compared to non-overlap designs (life testing). In addition, from a rework point of view, X-ray inspection yields no help when a failure occures. You can't det

Hany: I have never understood why the add-on boards in PCs have gold plating on their connectors. In the military and in avionics, they require gold on connectors to protect from wear and corrosion. But PCs ave very different. PCs: * Are obsolet
