I would like informnation regarding this high heat withstanding type material for PCB, also any other types that are compatible. We currently use FR4 but have an application that may require most advanced composition.

placement is only ok?, what size chip is this? Is the pad spacing correct? Are the apertures on your stencil reduced or 1:1. Stencil thickness? Do the problem areas heat up evenly? special plating on terminals of cap? Need more info.

I read your query and reccommend that you take a look at using Infra-red heating technology. I just joined PDR systems and feel that the PDR Technology is appropriate for what you are trying to accomplish. Hope this helps !!

My company is currently experimenting with with a 310 vox free water based flux on solder waves using Infared heat instead of forced convection. I'm interested if anyone has tried this and what results did you have

Hi there, I need some edge emitting laser mount, acting as heat sink also, seen once, from one Japanese company, if you have related info, please email me or reply here. Thanks, Jim

Another consideration is that heat damage is accumulative. If you have temperature sensitive components, that third reflow may be bringing them close to their failure point.

You can make bare BGA balls short together, depending on how you choose to heat the device. Lookit .. [http://davesmt.50megs.com/pictures/ select bgashortng.avi]

Does the thermal conductivity of a copper trace on a printed circuit board change as the copper oxidizes? Is the oxide on copper a thermal insulator? If so, should it be considered in an analysis of thermal resitivity between a ground plane and a h

Thermagon,Inc,in Cleveland,OH has a product line of high thermal conductivity circuit boards which you should investigate.Check www.thermagon.com and/or call Paul Klouda at 216-939-2310.The 216 area code might have changed to 440.

Rob: Wouldn't that only apply to IR ovens. If using a true convection oven the color of the material wouldn't hinder output at all "Right". Don�t want to see someone spend money on new tooling if unnecessary.
