It it PSA tape or heat seal? Every machine I have ever used has trouble with PSA cover tape. I wish they would ban in in ROHS. 3M tells me it is the future and it will replace heat seal tape.

Good luck finding used. Ersa is top quality but you pay for it. The IR from Ersa is a medium wavelength thus heating is consistent across the board despite different component densities and colors. PDR does not heat the same and thus you have to be m

What I would suggest trying is to only use your bottom heaters in your oven. In this way the board will receive the majority of the heat and conduct the heat to the component. Since your components are small and your board is more then twice the stan

I cant touch the pre-heat as it would affect all other products or so i am told by the Qaulity manager. Maybe they think i am Mickey Mouse and the pcb�s jump around the factory like a scene from Fantasia :) if this was only the truth.

Good afternoon, Heating/Cooling rates contribute to warpage most of all. Try to tweak you profile so that heating/cooling rate would be minimized. Try to switch cooling blowers off maintaining required peak/TAL. Check copper balance for this PWB, by

Hi Taint, Both machines work OK. The big thing you may over look is pre-heat. Things like flux spatter/boil tend to come into play if you don't pre-heat. Change over, ease of programming, and service are also things to think of.

It's some time difficult to control process when using a heat gun. What is the intent of using the heat gun after test?

That's how it's supposed to work, but is working correctly on the components that are loosing heat sinks for you? We have two choices: * Poor solderability of either the component or the heat sink ... OR * Wrong solder preform material

Thanks My mistake on the previous post is that the Temperature will be way beyond 90C maybe reach to 400c as the PCB will be placed under the Heating plate of the sandwich maker! So my concern is the heating tolerance! Appreciated your knowledge b

Hello Don, We dont heat cure any of our assemblies. We coat relitively few boards and just let them cure at room temp. Perhaps we should start heat curing. In fact, we have an old, fully functional, heller 1500 just sitting in storage. Hmmm. . .
