Reflow Process Index is designed to provide maximum quality and throughput from SMT reflow ovens. Helps manage reflow ovens to consistently maximize desired results. Provides process deficiency information to help correct defect issues quickly. Is an automatic system that, once programmed, works in the background without operator involvement. Shares all pertinent process and production data in real-time; automatically profiles every PCB; provides instant alarm for out-of-spec situations; automatic SPC charting, including Cpk; process traceability down to individual PCBs; prevents human error, such as production of the wrong PCBs or wrong oven recipe settings (barcode required).

PrinTEK I series benchtop SMT printers feature a synchronized 4-cam liftoff system, magnetic array table with locking pin-plates to easily tool the printed circuit board position, and rugged and accurate 3D via precision x, y, and theta anti-backlash adjustment heads. Basic printer handles PCBs up to 18" x 18"; large versions handle 18" x 24", and 24" x 36" boards. Optional patented dual squeegee gantry head and dual video microscope alignment system.

Sentry SMT pick-and-place on-board vision system has two modules: SIM and EPV. SIM (strobed inspection module) AOI system ensures no misplaced boards will be sent to the oven. EPV module (embedded process verification) evaluates errors detected by the SIM module. Process is recorded photographically in real time. SIM system consists of several single modules within the line, including high-speed focus cameras with integrated stroboscopic illumination. A master template of the assembled board to be produced is stored by the software. Board is scanned after screen printing to obtain master image, including 2- or 3-D paste inspection. Subsequent scan occurs between chip and IC assembly, then image is laid over master template and compared. SIM checks exact position of components on solder paste; component presence, tombstones, polarity, and dropped components. Requires no programming. EPV can be used as a standalone module or with SIM.

Pine-Shower reportedly removes flux residues, grease and other soils, and leaves a non-oily finish. Is said to be safe on ESD mats, work benches and equipment surfaces. Free of ionics and silicones that can contaminate PCBs. Contains no butyl cellosolve, is zero VOC, and has a less than 3% VOC under EPA guidelines. Is ready-to-use, or can be diluted for light surface and equipment cleaning.
