If you are looking to rework (after all of the previous suggestions are taken and tried....you have some solid ones in there). When a device like this is placed and is hard to get to we use the 7721 bumping process using a controlled heat source (no

Hi All, Currently we are producing a LED product using an aluminum core MCPCB with surface mount LEDs. In order to achieve better heat dissipation, we are considering transitioning over to a copper core MCPCB. My experience working with copper cor

Mcmaster only had white in that style. I had no problem finding spatulas or putty knives that fit the function of what I was looking for, it was more of the color green for visuals. Its just a nice touch for the visual. I may just dip the handles to

Doesn't look like it would be deliberately high temp for it's functionality or package type, unless it was accidental on a batch at the packaging plant. To get the datasheet you have to either go through the "request Info" on https://www.kingston.co

Jetting paste is no easy , ball mesh size and metal loading, SG and the dynamic rehology of the flux medium need to be matched to the jetting forces from the dispensing system. There are many jetting valve makers Musashi from Japan, Nordson Lyquidyn

Hi , thanks.. yes you are right.Its bot and top side. Decreasing the lower heaters and increasing the top heaters for secondary side. will this matter in convection reflow ovens. Since the heat at the end will get equally distributed. We were s

I also use these when available. The problem still persists for Bottom Paste/Parts layer. The non-symmetric(x axis) footprints in the Btm part layer, display correctly in the software, But then display incorrectly when imported into the Printer. The

Like I stated before, I am not familiar with the machine. I can only make suggestions. If you found solder paste on the nozzle, clean it off to prevent part stuck to the nozzle tip. I would also check if the nozzle tips are being worn off; uneven we

While I agree that you need to see an MD ASAP, it might help your provider to actually know what you were breathing, and I would worry way less about the materials in the components than I would about the flux from the solder paste. Edited to add, a
