PCB Assembly manufacturer Total Quality Management
All dimensions of measurement tools, ovens, heaters and pcb assembly sensitive type of equipment should be calibrated once for six months. ?-Ray thickness gauge, magnetic thickness, PTH resistance tester calibration date should be required.
Calibration should be measured by recognized standards bodies, pcba manufacturer quality assurance departments to the calibration of equipment, instruments, tools to register and to store the calibration record book. Calibrated equipment, instruments, measuring tools should be affixed to pass marked with the calibration error and the date and the date of the next should be calibrated, so it does not exceed the calibration period and not yet calibrated to continue to use the phenomenon. Quality Assurance department to develop instruments, equipment, measuring and calibration cycle calibration program, and should be responsible for regular supervision and inspection. Such as apparatus, equipment, damage or loss of precision measuring tools, should be ordered to stop using, until repair, calibration before using.
Seven, the handling of customer returns the product
Upon receipt of the customer to return the PCB, PCB assembly China and return to reason together with instructions to pay the person in charge of quality assurance department for processing. Quality assurance departments to designate a person seriously flawed inspection and returned to the PCB, to determine the reason for return is correct. Quality assurance personnel to the appropriate department head to rework some scrap, scrapped, ... the decision to the director (general manager) report, and should inform the customers requirements of production planning and sales departments to extract from the warehouse inventory replenishment scrapped product, pcb assembly or issued a plan to re-production. For repairing the product, to point out repair projects, parts, requiring rework methods. After repair the product to be checked again by the quality inspection personnel, stamped on each package containing a certificate can be shipped.
