Travis: I just checked. You're correct. It's a SMD-310, circa 1985 with a 12" wide mesh belt and a screamin' three zones of solder meltin' fury.

Currently using 3M 1181 tape. Purchasing has asked to try Argon CF200 tape. Has anyone used the Argon tape and is it worth switching to save a few bucks? Thanks for your input.

Could anyone please give me some insight on the time/temperature requirements for curing SMT adhesive used for a high temperature (96/4 solder) application in a bake oven, rather than using reflow? I understand that it would probably vary from epoxy

You're right, manufacturers time/temps will vary. A single manufacturer will have a host of materials with different cure schedules. We currently use 2 epoxies that cure in 2 - 3 minutes at 150�C. One will also cure in 5 minutes at 125�C. Talk t

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

An adhesive, is an adhesive, is an adhesive. Yes most will thin when exposed to elevated temperature, but that's only for a short time. As cross-linking starts, viscosity increases. Having made countless numbers of adhesively bonded samples in the

I used a Blue M batch oven quite a bit to cure in works great. All you have to do is get the board up to cure temperature, 150C normally and your all set. It will probably be in there longer than the time required but at that low temperature it shoul

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

Gary: It doesn't matter what you use to cure your glue. SMA adhesives are thermosets. This means they become hard on cure and this is not reversible. A couple of things go on with SMA adhesives when you heat them. * Their rheology is temperature
