That must have been really ,really cheap...... You sure it's 265 ?? what about the pre-heat?

My only explanation for this kind of thing happening, would be that (it's possible!) a pack of Crayons fell into the plastic mixture at the Chinese manufacturing plant. ;)

Regardless of the temperature, I would put jumper blocks on them first and discard them later. The jumper blocks should hold it in place and shield the metal, which draw heat faster than plastic.

I never have to do that,and I use both single and dual pin strip headers..... Lead free, flow soldered, 267 C , preheat 45 seconds @ 330C over hotplate, 1.2 M/sec

not much point in machine assembly if you have to manually put on jumper blocks and such ....

No need to do that for every other brand on the market, they survive quite nicely just like they are designed to do.

Yep, that figure comes direct form the board loader who were monitoring the temp as part of an initial pre-production run, it includes pre-heat.

I think you are right on the money!

How come there is no solder remnants on the pins?
