yigh, loose the glue, put paste on ALL bottom SMD components and cover ALL SMD components with peel off before wave.

Hi Loco, If i cover all the SMT component with peel off before reflow, it'll increasing downtime at my production site. To reduce the downtime, we had idea to add in the glue for component package 0805 and bigger.

Just curious...What is the gap between the pads? If it's less than 3 mm, it's recommended to do gang relief. Otherwise the soldermask will peel off during rework.

Looking at the different Selective solder machines. Are there any process considerations with a moving pot versus a fixed pot. What about the angle and peel off on the moving pot?

Be sure to peel the potatoes. I saw a guy use a potato to purify gold on the TV show Rough Science. Seriously though I would think SAC305 to SN100C wouldn't be as bad as eutectic to leadfree.

We have different Solder mask 'gloss' and 'satin' the gloss has a surface energy =40 dynes. The test evidence to date is strong correlation between surface energy, mask type, HASS failure

seen it many times before when the resist is not cured at manufacturing. get PCB man to check with K type thermal couple that boards ARE in fact cured. this is normally 155C ON board temperture not oven setting Cheers Greg

Hello, another SME is saying the solder resist cure level is suspect. I have had a industry SME make reference to this too. Adjusting the cure of the resist changes the surface energy

What is the humidity level in your facility? We maintain ~40% year round and never have any issues regarding ESD from cover tape peeling.

Anybody who could help me what is the tape peel off speed of PANASONIC CM602 for 8mm feeder? Appreciate your feedback.
