I searched the several internet sites and couldn't find a standard that
covers the following question:
What is the MINIMUM pin length in order to be able to reliably solder a
through-hole component to the PWB?
The pin diameter is 25mils. Hole diameter is 40mils. Pad diameter is hole
diameter + 15mils. Board thickness is 78mils.
Can you point me to a reference regarding this matter?
Thanks in advance for any assistance.
