(or just some static-safe foam tape) I need to seal a wire terminal block to a board for conformal coating purposes. Currently we glue it to a shim and glue the shim to the board (yuck), but I want to use die cut gaskets if I can make it cost effec

Hello ! Been googleing to find information for my boss that has no knowledge on SMT and the SMT area is new here so they hire me to work in these area, the thing is that without knowledge they put the line on the factory but without any safety preca

We use a Charge Plate Monitor (CPM) tp monitor the balance of our ionizers, according to ANSI ESD STM3.1. Maybe you could use a CPM to assess the ionizing radiation in your plant. The more we think about it, we feel you could use a Geiger-Mueller (G

Your image does not clearly explain the problem. However, I can see a good heel fillet formation at the joint. In general, TSOP leads are delicate and should handled with immense caution and good ESD protection. First let us be clear that any "rework

The problem expressed by you need not necessarily be caused by the Reflow process even though it's effect cannot be ruled out. I suggest to validate periodically the Reflow Oven performance as also optimise Reflow parameters through a documented vali

Smartasp, Seems this issue is certainly making a long thread ! As far as our Experience is concerned on Reflow Soldering, particular parts must have failed in LSLs [Lower Specification Limit] and have not withstand well under USLs [Upper Specificat

Dave, We have both situations where the grounded electrical equipment on the mat has insulative pads or does not have insulative pads. The workstations we have this problem with are test stations where electrical equipment is used on the test bench

Nuez, I don't really see how it's a problem. If your not using a wrist strap, there's no grounding issue. It will work fine as is, equipment insulated or not. The "conductive" mats have many mega-ohms of resistance as it is. Simply "bypassing" t

Advertisements are not always 100% accurate on technical issues. You don't want instand static discharge. A wrist strap with no resistor could cause that. Therefore put in a current limiting resistor to make the charge dissipate slowly. Does anyone

We're in the high reliability market and build to IPC Class 3 standards. I honestly don't know much about ESD but our in-house expert measured an 8kV charge on the board after printing with a plastic stencil and rubber squeegees. He wasn't too plea
