I just wanted to add a comment to the newbies, that dross must be recycled or it is considered a hazardous waste by the EPA. If you recycle it you can avoid a lot of documentation requirements needed for hazardous wastes, but you still need to have d

We don't use fussy things like that to remove mouse-bite tabs when they are not designed to be removed. Just cut away the majority of the waste using sheet metal shears. Then burr the remainder and the rough parts with a Sears wood router [bought a

There is a company I used call disaster recovery specialists when we a water leak in a moisture controlled environment as well as insurance a clamn customer had during a fire. If it is just dust that typically can be cleaned if it is smoke or mois

Sorry for not getting back sooner.. a virus attacked our network yesterday. The experiment you have outlined is what I had next on my list...just trying to see if anyone had done it before. We will be experimenting with 0.004" and 0.005" thick sten

At a previous employer we used a pneumatic dental type drill with nice results. The 1/4" hose is much more flexible than a flex drive cable, there's no motor module on the work surface, and the foot pedal for the air a little more elegant than two-h

Don't throw away the tapes ! We use vast quantities of component tape while testing our P&Pmachines. And mind you, we are normally not particular on what values the components have. ( For some tests we don't even need components in the tape. Its just

Dave, are you telling me that yer tryin' to pawn that off as a superscript "degree" symbol??? Wass' wrong with 183C, fer criminy's sake? (fighting urge for more defensive ranting) I'd swear a couple of old posts changed the way they displayed after

It is a serius problem with that mulilayer ceramic caps! In automotive applications you have to use 2 in series for one single cap. During depanelizing you create a mechanically wave in the board, so 3.. 4 mm. Best way is not to do such a wrong desig

In the early days of SMT we were using vibratory bulk feeders for chip components. It was quite obvious that some of the components had to try several times getting through the gravity trap or with the right side up through the light sensor. As a res

Your dust collection / humidity / ionic path concern is reasonable. Consider applying your conformal material thick enough to form a good barrier between the device edge and the board, similar to what you do for QFP. [Admittedly the QFP is not a pre
