SMT2220 In-Line Printer
The production line utilizes a SMT2220 In-Line printer for pick-and-place SMT assembly. With accurate printer alignment vision systems, the line facilitates high-speeds with the most precise component alignment. Alignment accuracy tolerance is to .0008" (1 pass), with 640H x 480V frame grabber resolution. |
 |
QuadIV Pick-and-Place Machine
The QuadIV pick-and-place machine grabs the components from the line feeders and places them on the solder pads. With accurate printer alignment vision systems, the line facilitates high-speeds with the most precise component alignment. Alignment accuracy tolerance is to .0008" (1 pass), with 640H x 480V frame grabber resolution. |

Vitronics Soltec Thermal Processing System
The Vitronics Soltec XPM thermal processing system produces outstanding levels of uniformity and repeatability in solder re-flow. The heat convection is transferred through the body of the IC package and the PWB and directly into the solder joints. Their flux flow control system removes flux contaminants from each zone, resulting in clean heated tunnels, |
 |
AATC Multi-Solvent Cleaner
The AATC multi-solvent cleaner is designed to wash, rinse, and dry backplanes and PCBs. This machine speeds up the cleaning process and remove solder residue from backplanes in large volumes. |
 |
The Nu/Clean 318 Aqueous Cleaner
This Nu/Clean 318 Cleaner is the high-pressure DI-Water base cleaner. It has a pre-wash chamber with 32 high-pressure spray nozzles, the wash chamber has 64 high-pressure spray nozzles, the rinse chamber has 80 high-pressure spray nozzles and the final rinse chamber has 12 high-pressure spray nozzles.
It has one 10 HP high performance wash pump, one 10 HP high performance rinse pump, and three 15 HP high performance turbine air blowers for high efficiency drying of printed circuit boards.
