Hi all,
I´m new in TechNet and I thanks in advance with any help you could
give me. I´m from Brazil, so I apologize about my english writing.
Well, my manufacture department is complaining with me that the PADs
I´m using is too small for a PQFP240 pins.
I used to have this dimensions:
PAD 50x10 mils
SOLDER MASK 50x10 mils
PASTE MASK 48x8 mils
And they are asking me to use this:
PAD 96x10 mils
SOLDER MASK 96x10 mils
PASTE MASK 94x8 mils
I would like to know which pad size you are using, as well as some
experience you have with fine-pitch pads.
We are using REFLOW process and Stencil with thickness 0.15mm
Thank you all,
