All depends on how accuracy you require -- Incase if the PCB layers are same along with same solder paste uses -- pls segregate as batch in terms of similar pcb dimension ( within 30cm variation) attach thermo couples to maximum area -- May be you ne

Hello! I want to inquire about settings for MPM printers with the Camalot inside system. We will use Koki JU-R45 adhesive and Koki S3X58-M406-3 solder paste with a 21ga needle. If anyone has a similar system, could you please share the initial parame

Leaded solder is liquidus at 183C, 220C is max. Sounds to me your boards might be contaminated or the plating is poor and allows oxidation. Without seeing the boards or profile, I recommend you slow down your oven for a longer soak, to allow the acti

Hi Dima, A past job used a PSE 300 from KOLB for 10 years. With proper maintenance, no problems were found. DST InJet was used in another production. As far as I know, there were no problems either. DST also has an interesting option, such as measuri

I wouldn't focus on the brands at all. you want the best features that meet your needs by the sounds of it. Koh young will be able to do a feedback loop to your current machines as well as their own brand. Maybe look into the reps of theirs in your

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

One thing that I did to eliminate 1 set of variables is I calculated the slowest belt speed that puts the board in reflow for the longest time spec'd for by the paste manufacturer. So every recipe runs at that belt speed. Eliminating the juggling o

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

If both BOM and CAD are Excel spreadsheets, you could write a routine to search the BOM for the REF DES, and then paste the Manuf PN from the column in that row. The issue becomes if you are searching for R1, it's going to find R10, R11, R12 etc. W

Flux is spec'd to match the paste & wires in use etc so I don't think we have an issue here. Bad Pad - what would I be looking for to confirm? I would say the pads look more tin than gold colour compared to normal so i am thinking it is some kind of
