Simulation of Placement Cpk on Paste

Simulation of Placement Cpk on Paste | 7 November, 2002

Hi all, I plan to measure the placement repeatability and accuracy.

Is there any work done to simulate the paste effects on test board without using paste (My measurement equipment is a back lighting equipment).

I saw someone placing components on gel or grease to simulate the paste effect on test board.

Any advise?

Thanks in advance bach

I used once flux cream on a glass plate for a customer application, which should simulate almost the same cohesion than solder paste.

Most of the printer and dispenser equipment companies job-out this glass plate analysis for the factory, pre-shipment verification of the capability of their equipment. Check with your equipment supplier, find-out the company they use [If they do it in-house, they certainly can recommend someone. They have to have considered out-sourcing that lab work in this day and age.], and contract with that service provider.
