Never had a problem with Samtec for sure. Sometimes engineers have to
fight a battle with purchasing. I foresaw a problem with a particular
component on a £750,000 contract some 20 years ago and pressurised
purchasing in the presence of board members to give extra lead time for
these, since we hadn't ordered that specific model in ages.
Did they ? Hell no ! It resulted in the ONE problem with project
completion, dealines and in-field reliability.
Many years ago, I worked for a plastics extruder, who got a contract to
make the plastic things that the customer then stuffed with pins. They
searched for WEEKS to find a plastic that could be extruded for less than
a king's ransom, yet still meet fire specs. The term 94V0 springs to mind,
but I couldn't swear to it. The plastic wasn't glass-filled - it was some
variety of vinyl, IIRC, but nothing was ever said about melting in service;
it was extruded at about 450 F, at which temp. it was still quite stiff.
The customer was happy with the result, but these were through-hole
headers, if that has anything to do with it.
Cheers!
