Sanjay: Keys to successful adhesive printing are: 1. Understanding the flow behavior of the adhesive under constant shear stress 2. Stencil design, i.e. stencil aperture opening 3. PWB Footprint 4. Stencil printing parameters Optimizing all these fac

Wait...stop! Some adhesives will void when cured... some common branks... maybe already mentioned. Heraeus PD955 will minimize voiding when curing the adhesive. Voiding can have devestating consequences....learned from experience. Another key is kee

We currently screen print all of our adhesive applications and generally have favorable results. The adhesive we use is: Heraeus , P/N 250 GM Prod/N PD955PR We print this on three different screen printers, Dek 265 Horizon, Fuji GSP-II and MPM-30

Dear Sanjay, An important issue involved when stencil printing adhesives vs. solder paste is: How do you clean the stencils after printing? Do you need two machines? Two chemistries? Two waste streams? What are the potential environmental impacts an

I sent you some adhesive printing application data from MPM and Epibond for review. There's good stuff in docs. Run the ppt file as a Show to get the animation.

We currently use Epibond 7275 with MPM printers. Unfortunately we've had problems with Vantico (formerly Ciba) providing a consistent product. Last summer we had extreme difficulty printing due to excessively high adhesive viscosity (20% higher tha
