The down and dirty method is to pop a part off using mechanical leverage. Otherwise you may be able to see it if you have a good Xray or CT.

Hi To perform a BGA repair of a 0402 size component, on a 23" x 18" board, is it necessary to preheat the entire board or only the area where it will be repaired? Thanks!

In general, no. If you've got the right BGA rework equipment, you should be able to locally heat the part area that you're reworking. Though, if you're finding defects related to thermal stress, it might not be a bad idea to pre-heat the rest of th

I have attached few X ray images along with its components. I am regularly getting this issue from the same component. What is the root cause for this?? Is it component issue or my process issues. Kindly enlight me.

Interesting one. I your machine placement algorithm capable to catch missing ball on the BGA while placing? Second question will be about component itself - datasheet will probably help. BGA body amterial? BGA balls alloy? BGA pad material before bal

Yes our M/C is having the capability. I will also double check it is enabled in this component. PCB - OSP finish. I will check the component data sheet for your other questions. Thanks for the response.

Hi, How to adjust the table height of Screen Printing EKRA X5? Could you share me the Manual System Operation?

How much adjustment is needed? Adjusting the snap off will get the PCB tighter/looser to the stencil. But this is only a 3 to -3 MM adjustment.

Hi Chris, It's arround +/- 2MM. There was a gap if running pcb with thickness 1MM. The PCB position below the rail table.
