On a wave solder pallet, we'd expect the metal parts that go through the pallet to be warmer than the pallet material, but we don't expect them to be warmer than the solder. We don't expect a well made board to blister at soldering temperature. So,

Hi all, I have a question regarding some wave pallets having metallic traces of Titanium. The solder mask is blistering in some locations on the PCB and I am wondering if this Titaniumn may have an influence by incresing locally the temp. Also we ar

Hi We have anew material that is very cost effective for solder pallets called Electro-Lock. You may find out more at http://www.rapidtool.com Kind regards dee claybrook

Necoleta, PWB Blistering/De-lamination may not be due for Titanium finished threads / holders which is typically being used to draw high Shelf Life of Pallets and even flow across Auto Wave Soldering rails. There is also nothing to suspect on Liquid

thk you very much for your fast answers. And yes, I am suspecting the same things also. The problem is to convince the PCB supplier that is his fault. A big fight all the time. SO, i will double check everything you said, and I willl come back with r

It is probably due to the solder mask being undercured and is porous alowing the flux to be absorbed which boils when it hits the solder wave that kills the adhesion. You should be seeing this only over copper traces/tracks. Reduce flux volume and in

Thanks Nicoleta It is nice to hear the problem is solved and this is a massive problem in the industry especially for Lead Free. It is easy for a supplier who doesn't understand to blame incompatibility just a quick way out but doesn't fix anything

Thank you for support. As i promised you, I am coming back with the results. The SM used was Probimer 77 with Kester 979 flux. The supplier says that there is an incompatibility and we have changed the flux with IF2009M. Same problem! They have chan

Can anyone give me any information on the longivity of titanium insert wave pallets. What I am looking for is the integrity of thin walls over several hundred cycles and the interface between the insert and the durostone material.

George, Who do you purchase your wave pallets from. Our vendors has not perfected this attachment yet and I need to get a source. Thanks, KSRSR
