Check with Dupont's web site. They have a wealth of information on the various polyimide products they manufacture. I was quite surrised at the differences in materials and in particular the dimensional stability and hydroscopy. Good stuff mayna

Thanks Dave, From what I remember a lot of components went away from Silver Palladium to "base metal" terminations because of the difficulties in continuation of supply & stability of price. (Something about being mined in Chechnia or the Congo?) W

You are not wrong in monitoring the Product (your really not monitoring the process). This methodology is valuable if your process is unstable (SPC is used to stabilize process). There is value in "real time" inspection of a process's product as lon

It really depends on what deliverables BTU can offer and successfully accomplish without the complexity of various reinvention activities. The basis of its� vehicle stability as a total platform should be broken into a framework of goals and objecti

Ungar used to sell a little tube of clear stuff that they called something like "tip anti-seize". I used it on Imperial irons, back in the days before electronic temperature control. The pure copper threads on the heating element would seize to the

NEITHER AXI nor AOI are "stable" or "repeatable." If your false call rate is zero, then you've basically rendered the machine an expensive conveyor (ie it's passing everything 'cause you've opened the limits too much). You can *try* to do a Cpk or

You can get an used GSM1 for little money, used pneumatic feeders are cheap and reliable. Software is excellent and there's a lot of spares on the second-hand market. Initial investment is low and you get excellent machine, superbly built, that will

I always fix thermocouples to pcb pads across its width. Then rotate it 180 degrees to check readings. If I am happy that the oven is giving results within a few degrees C then I'll crack on and set up a soldering profile. I am not sure what the oven

Stephen, Bill, Thaks for your input. We are currently waiting for nozzles since the ones we have are badly oxidized. We do have a deoxidizing gel that we got from ERSA, not sure if it contains Adipic Acid, but it is what was suggested we used. Once
