| I recently had the opportunity to visit the vendor who is making my boards. On my trip I noticed that the guy who was in charge of the SMD placement machine (brand new Samsung) still had to manuallly place about 20%-40% of the parts after placement

Thanks for the tip. I'm still getting familiar with the machine by reading the manuals as I have time. Was wondering what type of solvent you use to clean the dispensing mechanism parts? Or do you not clean anything and simply dispose of the syring p

Oh yeah, so we have a auger valve similar to that on one of our other machines that we use for dispensing SMT glue, and solder paste also. We have a conditioner that we flush it with at EOD when in use, then we just let it sit idle with the condition

| WOULD LIKE TO DO RELOW OF 2 SIDED SMT BOARDS. USUALLY THE BOTTOM SIDE HAS RESISTORS AND CAPS ONLY. WHEN THE BOTTOM OF THE BOARD HEATS UP, THE PARTS ARE FREE TO MOVE AND ONLY SURFACE TENSION WILL KEEP THE COMPONENT FROM FALLING OFF. | CAN BOARDS BE

For protos and very short runs I already use a polyester stencil + pizza oven process which is fine except for the placement time and tedium. I'm partly trying to bridge the gap between that and stuff that needs subbing out due to quantity, and partl

We do this quote often with our older Summit machine. there are a few ways to do this. all of these are assuming you have parts on the boards already and are working around them. 1- if you have a good tech that can add solder to the pads on the PCB a

Just a note about cleaning SMD adhesives. Cleaning does not need to be hazardous. Smart Sonic has a non hazardous process that has been used for over 9 years using a non hazardous detergent that has been certified by the AQMD as a clean air chemist
