Is there a way or process to use the screen printer to put solder paste in the thru holes ? The thing is that we are trying to put a thru hole in the same reflow oven with the other SMD components can some one explain how this work? thanks

We do a lot of intrusive reflow. It works very well but the others are correct you need to verify that the part can survive the high temps. Most TH components are not rated for reflow, we have to test each one ourselves.

I agree I thought all MYData's had them built in. If not I'd contact MYData and see what they recommend. You can find their contact infor on their website http://www.mydata.com.

How thick is the stencil? Also what type of paste? We have a nice little microscope that has gradients on the lens so we can measure whether an aperture is 8 thou or not. Almost always it is but then we buy from a couple of good stencil suppliers.

A lot of our dewetting is happening on plastic body components, such as ICs. When they are manufactured, the molding process requires a mold release to make the part release after molding. Usually, the release agent is silicon based, but you can't

I am planning on trying to autospray CE 1155 using an SCS precision coat. Does anyone out there currently do this? If so, can you share any information and parameters such as mixtures, methods, head configuration, conveyor baking. ANY information

Am looking for a dispensable water soluble solder mask or peelable solder mask that can be dispensed and be run through a reflow oven with no swelling or degradation. Any leads on any materials or manufacturers to contact?

Can anyone give me suggestions on tape used for masking. Of course, I am looking for the "perfect tape" that sticks well, is flexible, offers lubricity for rubbing the tape, does not leave adhesive, easily removed for demasking, and won't leacvh any

ATS-667 tape. You can buy direct http://www.ats24.com/index.cfm?fuseaction=content.display&contentid=50 or through distribution such as All-Spec. Polyester film with rubber resin adhesive (no silicone) = clean mask lines. Call for a sample.

I am new Engineer in conformal coating and I am looking for help with dewetting. What "Tricks of the trade" can I try to reduce or eliminate dewetting? We use a lot of Conap CE 1155 and Humiseal 1B73? Any help would be appreciated!!!
