OK, I know that - I thought there was some other additional technology :)

How about adding preforms?

| | On various PCB's after building processes,such as reflow, flowsolder and wash. The soldermask on the PCB's have become discoloured, like a 'marble' effect all along the solder side of the board, it is lighter in contrast than normal, although whe

I almost always go with an overprint as long as it's feasible. I haven't had much problem with solder-balling when overprinting. I'd give it a try and see how it works for you.

Depends on the product & constraints your having to deal with. I've used the following in the past; Stepped Stencil, Overprint, Additional dispensing equipment after the print process & Solder pre forms

Do you have capability to individually add extra paste to pads through hand deposit or with a machine like a Camalot dispenser?

Michal, Overprinting is the extension of the stencil aperture over the solder mask, to enable a bigger volume of solder paste on the pad, therefore bigger volume of the solder joint after reflow. https://youtu.be/WAIm-6BSaiQ?si=UMp9WSFal3vXFp8F as

We have an application requiring more than a single preform per component (PIP through hole socket). What we found out is that regardless of how much you overprint, the flux contained in the paste is not enough, so we ended up needing to dispense gel

Hello, We have problems with insufficient solder volume on a component. To solve this problem, we want to add more paste to the component. We have two options for this: 1. run a stencil with a step to achieve the required volume. 2. overprinting
