Hi, For bonding jumper wires to a PCB surface we use the Tak Pak series of instant adhesives. Bonds in a few seconds. Is there something better? Inquiring minds want to know.

We borrowed a UV cure wand from them and tried some UV cure materials. Worked well, but I couldn't cost justify it for the project - it was to bond some jumper wires. regards, - Graham -----Original Message----- From: Genny Gibbard [mailto:[log in to unmask]] Sent: Friday, March 06, 2009 12:51 PM To: TechNet E-Mail Forum; Collins, Graham (FN) @ ESI Subject: RE: [TN] Coatings, epoxies, etc crash course Thanks. The general principle of UV curing sounds fantastic, but it's a bit of which came first - chicken or the egg... We've never used UV cure materials here, and we don't have any of the equipment to do it. I looked into it a bit last year, but like I said in different words below, 'I don't know what I don't know'. I don't know exactly what I need for equipment, or what material to use where, and I don't know how to get up to speed on this process. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Graham Collins Sent: March 6, 2009 10:46 AM To: [log in to unmask] Subject: Re: [TN] Coatings, epoxies, etc crash course A UV cure material? regards, - Graham -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Genny Gibbard Sent: Friday, March 06, 2009 12:35 PM To: [log in to unmask] Subject: [TN] Coatings, epoxies, etc crash course Hello all, I do a lot of component and material sourcing, crossing, and spec'ing. Probably the area I struggle with the most is the materials, like epoxies for board repairs, or adhesives, or sealants, cleaners, etc etc,...I did electrical engineering, not chemical. Is there any good resource place to get a handle on when you want an acrylic versus an epoxy, or silicone, or ... basic properties, what environment they are needed for, etc. A specific sourcing question I have right now - for challenging board repairs we use specially trained operators in a rework cell that use a 2-part epoxy to repair FR4. One product has a track cut, that usually causes weave exposure, that happens on every board on the line to allow for different configurations, and they want a way to protect it adequately with a 1-part quick curing material without sending it to the rework cell. We've tried those conformal coat pens, and they can be washed right off the board. Any suggestions?
