Thanks Rob. I'm not so sure in a mass production environment that using the mount spray and kapton tapes are going to be efficient. For solder paste dispensing, any idea what is the smallest solder dot size the machine can dispense?

Hi Rob, So do you have to constantly remove the old adhesive and spray on new ones? Is that an automated process? Also for the kapton tape removal and application, is that automated as well?

Preemptively you can apply Kapton tape to protect the gold fingers during reflow. I think that's what most people do. After the fact, there are services available to clean them up but as it was described in another thread here, it is not in-expensiv

Hi, thanks for reply. Kapton tape is costly and it may create another handling issue. BTW can you share the thread for the cleaning process ?

For volume we used machined pocket durastone pallets, machined to the thickness of the flex to allow flat printing, with pockets machined for components placed on side 1. We held them down with 3M spray mount. For low volumes we used flat durastone

Print no paste on the tin-plated, [test???] pad. Experiment by putting Kapton tape over the stencil aperture for the tin platted pad. Re-assess your reflow profile, since the liquidus of the two plating materials will be different. Evaluate your pa

You can also cover unused part with Kapton tape on the bottom side of the stencil. We did it in the past, but today you can order stencils from JLC for almost nothing, so...

I feel your pain. Your company may already be using Kapton tape labels for their board serial numbers labels. Kapton is able to withstand repeated wash and heat cycles, and can be printed on a typical Zebra printer. The key to a successful and accura

If you have room try putting a small piece of tape on the bottom of the stencil right next the aperture that is giving you the problem. The added height of the tape (Kapton tape is usually about 3 mils thick) will likely give you a heavy enough depo

Hi Daniele: In a design of experiments with four methods for attaching thermocouples : High Temperature Solder, Aluminum Tape (Chomerics T405), Kapton Tape and Conductive Epoxy (Loctite Tak Pak 382. The most reliable method is high temperature solde
