| | | Can anyone steer me towards a supplier of heatsinks suitable for use on a PQFP 160. Before you shoot me down in flames, I know that I am not going to get much heat away from the die because of the plastic but the application is such that the bo

(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

Install a gasket made of a non-esd safe material that can be die cut at a station equiped with an ionizer.

I�m unclear about the intent of your question, but I�ll take a pass at it regardless. I second the previous poster's commets. [Ya, that's the ticket.] Most chip attach adhesives should not be cured at typical reflow profile temperatures. Check yo

Set Up Guy, I am not sure if the COB you are refering to means Circuit on Board . If yes, this process also include SMT . Package is a combination of some passive components and bare die. Passives are normally attached thru SMT using solder te

The pressure sensitive tape is used as an alternative to heat sealed cover tape. It works usually quite well and is easily applied by the taping machine, but it can create some problems in the tape feeder. In the Surftape, Cal is referring to, the c

Thank you ur reply Dave. Let me explain our COB workflow: 1. unpack PCB (FR4,LPI,HASL)(the thickness of gold and nickel we can't be find)(No SMT before) 2. clean the pcb by rubber 3. blow the pcb by di-ionic gun 4. attach die by adhesive gel 5. cure

I am attaching bare die using conductive epoxy. Thanks, Chris

I have not looked into eutectic die attach. My dies are about .012" square and could get smaller. Currently using a Epoxytech conductive adhesive. I am going to go out and look at equipment and build samples. Some vendores state they can do .010"

Hello Chris, If you could humor me, what are the limiting factors forcing your dot size to .010"? What is the die size that you are placing? What are the accuracy tolerances? Was eutectic die attach never an option for this bare die? Have you de
