] Date Posted: 08:55:17 01/31/04 Sat The simple timed / temperature setting of preheaters in a soldering operation has been up to now a trial and error process, involving conveyor speeds, heater drive power, board configuration, &c., and hours with a profiler system to keep the process in check. Using advanced infra red pyrometry technology, the Equipment Engineering Company developed a simple, cheap, accurate and reliable method of "closed loop" controlling ANY preheater: any component can be monitored to eliminate any possibility of a more susceptable component becoming overheated before the main board has reached a suitable temperature. The pyrometers can detect poorly performing heater stations, occluded cover glass, damaged filaments, out of spec. long wavelength heaters. The system can be configured to flag a warning, and after a programmable number of errors, stop up a machine to prevent scrap or out of spec. product. Full information and prices from OPTL, England, who are the sole agents. [ Next Thread | Previous Thread | Next Message | Previous Message ] |
