Try: Tungsten, tungsten carbide, ceramics like boron-nitride or how about pyrex glass? Glass blowers could make "hooks" that connect to a cross bar. I would NOT use aluminum (even if anodized). Try stainless steel 316. 303, 304 do not have enough

Has anyone experienced electrical shorting between adjacent leads of a ceramic hermatic sealed IC? If so, can you share root cause and corrective action? The shorting appears to be in the glass frit seal itself but the failure mechanism is unknown. A

| Read an earlier thread about using glass slugs to determine placement CPk. Can it actually be done this way? What's the procedure? Be interesting to know 'cause if it's feasible, I'd probably get myself a kit. None of us here are stat's experts

We process no Teflon boards. Companies, such as Rogers and Taconic, make laminates of Polytetrafluoroethylene [PTFE] er �Teflon�. Common �Teflon� laminates are: * Woven glass / PTFE * Random microfiber glass / PTFE * Ceramic / PTFE * Woven glass /

FUJI DUDE- You can purchase a Kit from IPC for verifying machine acceptability. IPC-9850 full kit with Components and boards, and such will set you back around $26,250 (member price). Just the glass board alone will cost you $3,800 (member Price).Thi

Marc: In printed circuit board fabrication, fabricators place sheets of prepreg between each pair of glass cores. They stack these layers into books. As they heat and press the books, the sheet melts into an epoxy glue. The thickness of the prepr

Again, I'm not familiar with your material but SMT Adhesives as a collective group are typically hydroscopic. An increase in humidity in your facility will lower the viscosity of certain materials. I don't want to say who's material I've had bad ex

We�ve also had glass diode difficulties- poor adhesion while all other parts are fine (including tall parts). I�ve received some interesting information from Heraeus: It seems the newer glues create a much stronger bond to SMD�s, except glass diodes.
