Hello Cor, I want to introduce myself and my company. TMP. Worldwide. I
am Sharon Gheen I have the express honor of being part of the IPC. I do
work full time for the leading Technical Staffing firm in the WORLD.
Honestly!! Check us out on the web.. Anyway I was hoping that I might call
you to chat. I am always looking for designers and positions for designers.
Since the PCB design community is really so closely knit, I like to meet and
net work with all the talented designers I can. Would it be ok for me to
call you? (I'll need your number) Or I have inserted all my phone numbers.
Thanks so much for your time. Enjoy the weekend. Sincerely
Sharon

Subject: [DC] Paste screening of Through Hole Test Vias
Hello to all of you,
Currently,we are designing a double sided reflow board.
All our assembled boards have to pass electrical test, preferably on a bed
of nails.
Is it good practice to close all through hole testvias by paste screening
in order to create good
vacuum conditions when testing ?
So, I want to include these vias in the paste screen artwork. What is a
good diameter in the paste
screen for closing vias with a finished hole diameter of 8 mil ?
Is there not a risk that the solder paste will flow through the via holes
and causing shorts at the other side
during the second step of reflowing ? The board has a thickness of 95 mil.
Anyone has some experience in this matter ?
Thanks in advance.
Cor Coolen
Board Designer
