Is any one else having a problem with parts that are Ni/Sn plated? The parts in question are a 1206 voltage suppressor form AVX. I am still using a stander 63/37 solder paste which is according to AVX�s web sight compatible with this plating. The

It seems like the break is happening between the sn and ni. The parts are dull in appearance will not take solder even with an iron after they come off so it leads me to believe that there is only ni left on the part. The parts are liquidous for ab

Hi Guys, Can you give me a good bird's eye view in Verifying First Off via ICT Test. We currently verify our first off via naked eye for just the solder joint quality, orientation of parts etc. Aside from open and shorts, what can ICT verify? how c

We are launching a new product and are fairly new to reflow soldering. A concern that has arisen is a fairly consistent solder ball that forms at an electrolytic capacitor. We changed to a homebase aperture design on our passives to eliminate mid-c

many solder-ball issues can be resolved by reducing the aperture size, usually 10 to 15% reduction will work. If the aperture size is the same as the pad size paste tends to be squished out under the part, paste off pad under the part will liquify a

Our "mechanical engineering dominated" company is allowing the electrical group to purchase some software to produce machine wiring diagrams. The only stipulation is that it has to be low cost. Can anyone throw out any products? I'm not looking fo

Just an idea... Try investigating methods for storing large drawings. We have a hanging file cabinet for E size drawings. You apply a self adhesive strip of mylar to the end of the drawing that has four holes in it. The cabinet opens up and 2 sets

We have a cabinet that holds all of our stencils. It is a homemade cabinet made to fit stencils with about 12 drawers and each drawer holds about 10 stencils. Each drawer is labeled with the stencil# for each stencil. When a new stencil comes in we j

An issue just came up concerning the color of FR-4. By accident we received a prototype board that was blue. We like the looks of it but can not justify a change because it looks cool. My questions are: 1: Why are most common PCB's green? 2: What are

Q1: Why are most common PCB's green? A1: Tradition Q2: What are the tradeoffs, ie electrical characteristics, etc for changing board colors? Q2: None. We use different colored solder mask on boards to indicate different development stages. See you
