Well, the precision glass is for upward looking camera's. It essentially is a "perfect part". Vapor deposition lithography on glass (for Cte stability)....basically the part pattern (or part fids) is compared to its target location (same pattern on

Unfortunately, smt machines are not like TH sequencers. But, that is in their favor. Multiple reels, multiple part types, many positions = very flexible. Offline setup is paramount to line utilization. Remember, you only make money when the machi

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

At the 2004 IMAPS Nordic Conference, Claus W�rtz Nielsson from Nokia Mobile Phones published "The Evolution of Surface Finishes in Mobile Phone Applications" [www.imaps.org/adv_micro/papers/Nordic2004paper.pdf]. Some of the results were: * Corrosion

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
