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

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
