I have one product which only need print low temperature solder paste on OSP pad. This pad will used for hot bar process. Desired solder paste thickness is 0.10 mm to 0.15 mm. Is any one can advise right stencil thickness and aperture opening for it.

Hi! Just joined the circuit. Hot Bar soldering is very reliable provided the Flexible Printed Circuit (FPC) and Rigid PCB design support this technique. Some of the critical aspects that need to be considered include Stencil apperture design for sold

The sole soldering quality standard that we are aware of is A-610.

Hi Dave, Would this be different from IPC-610-D. I am not sure.

No. They're the same ... A-610 and IPC-A-610

Any acceptance criteria for hot bar soldering finishing? e.g. IPC-A-610? or anything else?

Yes I agree with Emil that the Jig/Fixture design is crucial for alignment. The hot-bar machine I worked with came with a digital camera and monitor to aid with alignment. Other than that, the right profile (heat, pressure and dwell), and a good fl

Watch out for workmanship specs. I don't believe this is covered under IPC-A-610. You may have to write your own. Alignment of the fixture and coplanarity of the bar and substrate are key. Also, pay close attention to stencil aperture and thicknes

Omar: I dealt with this so called "hot bar" process also, and you're right; it's neither reliable nor repeatable. The goal was to attach a flex LCD display to another flex circuit. The flex LCD was constructed of resin and conductive silver particl
