AJ, We use all ENIG boards. After opening, any remaining boards are kept in low humidity keeping cabinet. I have never experienced a problem using this method I think the longest I have kept them this way is eighteen months. We also store any open tr

Dave, I have never even seen black pad - even in my subby days. As my wife says whenever I find a good parking spot: "Lucky Darby and his beautiful wife!" This is particularly so if we go to Watto�s - www.sydneypubguide.net/pubs/Watsons_Bay_Hotel_(D

Once a rock star, always a rock star, eh bubba? Ozz don't forget stuff like that. After a half liter of golden merriment, I don't care about how odd the food tastes, I just want to remain agile enough to dodge the sinkholes on the way home.

Hi, Could it be shocks in transit? This is only happening on 1 product, so might point to chassis and packing design. Does anyone know of any shock indicators that we could put inside the chassis to see if the faults are caused by this? I have seen

The need to Pre-Bake depends on multiple variables: 1. Packaging from the vendor (dry packs, vacuum sealed, etc...) 2. Storage at your facility (temp, humidity, etc...) 3. Moisture absortion rate of Laminate (FR406BC is one of the highest) Other rea

What is a foolproof means of eliminating moisture content from Printed Circuits that arrive (bot hpurchased and consigned) in unsealed, non-dessicant packed bags? Als, is there a procedure for basic mass of boards vs. temp/cure times? I need to min

Moisture barrier bags are polymer coated foil so are nearly gas impermeable. There's always some coating left at the weld (or it wouldn't stick) so they're not completely sealed but that's as good as it gets. Usually people use the vacuum to remove

Jay Go to the Services menu and then station configuration. Choose your F3 machine from the list. This will open the tool that allows you to configure what the machine has on it. Look to see if you have a box with the following: WPC-TR S_WPW_80F

Prior to packing the boards, we cover the marking on the IC by dispensing epoxy on top it. This is a way to protect our design so no one can copy it. We have a lot of boards and the optr takes a long time doing it manually. im thinking of using a pne

Our front panels (where the controls show) for our assembled amplifiers are anodized and we make sure that it is free from oils or other stains prior packing the whole assembled unit. We just use damp cloth in cleaning and sometimes flux remover for
