Generally speaking with most electronic grade epoxies: 1. Cure time is a function of temperature. 2. Polymer bonds begin to quickly break down above certain temperatures (product specific). I believe aprox 170-180C. The strength of the bond de

| Hi Stoney, | Justin is giving you some good advice, unfortunately these kinda' problems sometimes call for the ol' D.O.E...otherwise, you could be chasing your tail for a while until you figure out exactly what's causing your problems. | Has

Cheers guys for your rapid response, I investigated the problem further today, eventually I cam round to curing the adhesive in a sandwich of microscope slides resting on the PCA in question (hopefully mimicking the heat transfer), the adhesive is sp

Try 3616 or 3609. Both of these become pliable when heat is applied.

Any decent flux would volatise off with the heat of the wave unless absorbed into the solder mask. Test this by trying to clean in alcohol or common solvent aerosol, if it does not clean then it is probably Mineral Salts from solder mask fillers. Ano

Hi Greg, We've used lots of machines over the years & seen lots of different tape related issues - the main one being snap off of the cover tape, usually due to too much glue, over entusiastic heat seal, or a feeder requiring maintainance. Also the

We have been pretty successful with screen printing glue, however the smallest component we now glue is a 0805. We had many problems using our Gemini II to put down glue dots for a 0603, so we altered the pads to do double-side reflow. As our own int

Russ, Are you placing 0402's on glue by using a stenil at present? I am afraid the appertures will be too small for the glue to release from the stencil. Are you having any issues with this? Thank you for the reply. Mike
