If the sales type can not provide the information you require, you are buying from the wrong company.

We used durastone, with a profile routed out to expose certain areas & protect others. Durastone costs peanuts, and the tool room uses a small cheap Micromat router.

Hi Rob Can you please tell me where you can get durastone for peanuts as I find it quite expensive.

Hi Ken, There may be different composites of Durastone, but there are certainly mixes out there that are. http://www.ascenteceng.com/resources/materials.html We used durastone as a carrier for flex circuits as well. Cheers, Rob.

Round cracks that look like it's from a placement are generally from a too big Delta T in wave (been there done that). All other cracks are anomalies. Ya gotta see it find it.

Questions are: * What is the scale and scope of the problem? * What does the unfilled portion of the barrel look like? * What class of flux is your solder paste?

I would definitely try a more agressive flux. Are you using a W.S. or No-Clean? And of course check the usual preheat temp flux application dwell time immersion depth

Surely this is a job for Wavemaster Larry? Have you tried flux buster pins in your ICT yet? They are quite good at cutting through the crap on a board.
