We use the very common industry standard Loctite 3609 (RED) chipbonder in our process. However, one of our new customers requires that we build on RED PCB fabs. Thus our challenge when trying to inspect the bottomside epoxy. ANYONE KNOW OF ANY OTHE

We used Loctite 3609 and never had problems. If memory serves me isn't 3606 a screen print adhesive? First thing I would check is the cure profile of the adhesive. If it doesn't develop full adhesion, could be problems. Nuther question is are you

Guy's another question, how about any recommendation what type of adhesive to use as underfill for BGA during lead free process? Currently, we are only using Loctite 3609 & 3515 as adhesive we use 3515 as BGA underfill during normal leaded process s

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

Charlie: People cure glue using their paste reflow profile all the time. And most of them are happy. Personally, I�m with Dean and Travis. It�s possible to as you suggest, it�s appealing not to mess with your oven profile, but it just doesn�t s

I appreciate both of your responses. I spoke with a tech rep at a distributor of the Loctite 3609 and asked him if this adhesive can be cured using a bake oven (Blue M, Despatch, etc.), rather than convection/IR. He stated that he's never heard of

I am developing a D.O.E for Surface Mount Adhesives and was wondering if anyone out there had any recommendations on a certain brand. I currently have samples of Loctite 3609, 3615, 3618, Heraeus PD955M and MA-420 by Lord Chemicals. I understand Ci

I hope that someone can help me with my problem! I am experiencing a lot of glued on parts falling off in the wave solder machine. A little information about my process: 1)We use Loctite 3609 glue that is used up long before its shelf life 2)Our pa

I am developing a DOE for evaluating SMT adhesives. I would like to evaluate 3 different vendor dispensing adhesives. I currently have the Heraeus PD955M and the Loctite 3609 and 3618 selected for evaluation. I would like to add another manufactur
