Just get a regular scale(small thin one - like a scale for kitchen). Mount it over a PCB and simulate placement with certain force. Hold the nozzle down for long time in order to register accurate reading from the scale. Then, just change parameters

Beware the foam fluxer. I had a problem with cracked caps that just about drove me off the deep end. I discovered that my foam fluxer air knife was not turned on resulting in excessive flux. The excessive flux (VOC free) was not properly dried off

I'm confused ... Land Grid Array (LGA). An alternative to the BGA for device manufacturers is to package their devices without any terminations on the bottom. Although not technically accurate, the easiest way to envision an LGA device is to pictu

Two options: 1 Glue 2 Use a dedicated work holder with 'pockets' milled out to accommodate the components on the first side of the board after reflow. Some prefer a pallet that runs all the way through their process. So, these pallets: * Feature

We have been processing a 3 and 5 up flex array for nearly four years on pallets and have had a pretty steep learning curve. Make sure you have vacuum holes in your pallet for the screen printing process, also work with your support block vendor to

There are several things that can cause these errors. It sounds as if you have 2 problems. A (Z) problem and a theta problem. 1. Check that the Z-locks are functioning properly in the service program. Make sure that when they are un-locked they don'

Here is the problem : We have 2 AP25 printers with dedicated tooling. After we run side one boards through reflow, we get some warpage in our boards occasionally.(Sometimes we get a lot of warp depending on the geometries of the substrate) When the

Hi. I agree that the Soltec has weak, low-wattage preheaters, and also, the Soltec's fluxer is flippin' weak too. It doesn't do a good jab of atomizing the flux and getting good, huh-huh, penetration on the holes. I cranked up my Soltec's pressu
