Balancing between cost and tester acceptance in case of new product introduction for PCB assembly

Companies which are offering electronic manufacturing services are continuously balancing among fast product introduction of customer products, high quality production and profitable operation. Our paper describes link among producability of PCB boards, process control, test system & equipments reliability and profitabile manufacturing process control is key in PCB assembly for high quality and profitable operation, however the time pressure limits the development of product test system which is the core of control of board assembly. In order to achieve good control appropriate methods and equipments are essential assets. To be ahead of competition method and process were developed which can be used in production environment for tester system and regular check of condition of tester system. Beside of a product test coverage the production test system reliability and long term reliability is calculated with the help of statistical methods. The acceptance method can be used both for own product test system development and also for consigned equipments.
