QFP on going on square (now and again) | 2 April, 2013

On one of the products uses a QFP (Quad Flat Package)which is not going on straight, maybe 20 pins per 4 sides. sometimes I have to tweak the alignment before the board goes in the oven, this practice can be a bit of a worry if you over tweak it - paste gets in between the pins, then when it comes out of the oven, there is lots of pin solder shorts.

I notice the JUKI nozzle (#105) has a rubber grommet on it, and it is showing signs that the rubber is getting a bit passed it. I wonder if you can get a repair kit consisting on a rubber grommet.

This is where I purchase nozzles for our Jukis. You don't have to purchase the entire nozzle assembly, just the tip and slider...

I don't have any affiliation with this company, just a happy customer.

Thank you for that, I see the #106 nozzle looks in better shape (with the rubber) I might try that nozzle and see how it goes on a few boards, then I could let the "higher authority" know.
