ESD Smocks and chairs

Electronics Forum | Tue Jun 19 21:44:20 EDT 2007 | rfrog

The first thing that I would do is contact the smock manufacturer and ask them for advice on testing the smocks. ESD FROM A TO Z 2nd ed. (Kolyer) states that: smocks should have a resistivity of less than 10^12/sq and must not shed steel fibers.

Board change and solder not adhereing completely

Electronics Forum | Fri Apr 06 04:10:25 EDT 2001 | kensmoke

We recently had a multi block panal change at the vendor Now the production lines are producing solderability defects in great number. The makeup of the pcb is a type of fiber glass mask green in color and pads with no tinning just copper lands.

It must be at least a little more ESD safe than a polyester sweater. And I'm sure at least at sometime someone has worn some clothing made of plastic fibers at your place. basically find the worst thing you allow, (probably polyester sweaters) and

Thinner: Flux thinner, NOT paint thinner We kept a spare stone in thinner in inventory. We cut PVC pipe to size, cap in one end, screw thread on the other, stone inside, filled with flux thinner and covered with a screw cap. I don't remember who we

Certainly could be true - so do we keep producing with toxics or find a better way? So far, lead is on its way out, as for the others, it will take time to qualify and quantify the true cause and effects, meanwhile why aren't we going fiber optics be

| Recently, there has been an upsurge in the Pin Hole/Blow Hole problem in our wave soldering process. We are baking the PCBs for 2 Hrs. at 125 degree C. The Wave Soldering profile seems to be O.K. Still the problem is persistent. Can somebody hel

programming SMD flash memory and SMD flash memory in microcontrollers before PCB assembly

Electronics Forum | Fri Jan 15 05:33:05 EST 2016 | jvercamm

hi, I would like to know if SMD parts (soic, small qfp, large qfp and tsop parts) can be programmed before PCB assembly and, if true, which companies can do this. These parts are either embedded microcontrollers with flash memory, flash memory and

ENIG again! Failed BGA joint!

Electronics Forum | Tue May 08 15:05:08 EDT 2001 | davef

It�s reasonable to want to understand this strange looking fabrication, before moving on to other issues. Before moving on to that, tell us more about your thinking the silicon being from the BGA package. What kind of plastic package is this? Desc
