Process description : MQA system will divide all key process into 4 stage a.​ Quality Planning : -​ Quality Manual : The first level quality document and the instruction for all quality activity. -​ Control plan : A control plan is a list of product characteristics and manufacturing parameters that will be monitored . It should show the link between customer requirements and manufacturing control by specification of product characteristics and quality concered. -​ Contract review : 1.​ RFQ meeting : Customer requirement survey including Spec. / cost / quantity …. 2.​ CB : Introduce the customer requirement into BCU system -​ New project : The scope should included process /equipment/product introduction . b.​ Quality infrastructure : -​ Supplier Management : Component Quality Assurance and Supplier Quality Assurance form essential activities of the BCU Monitors management process. -​ Process Management : The management should include 1.​ Machine capability study : Equipment will be qualified by using statistical techniques. Cmk values will meet the goal . The evaluation should include : New or existing equipment . 2.​ Process capability : Through SPC (Statistical Process Control) to achieve process key parameter control and approach the maximum process ability with satisfactory quality . 3.​ Quality inspection and test plan ( from incomping to shipping) : The inspection and test plan include first article inspection and inprocess inspection and test / Final inspection and outgoing quality assessment / Sampling plan for incoming material and outgoing products / Out of box audit -​ Quality improve : Continuous quality improvement is our approach , field repair and DOA item from our customer ; high fall off rate issue and reliability test result from production will be transferred to our quality improvement action . c.​ Quality execution -​ Physical handling : The handling include 3 field 1.​ Receiving operation control 2.​ Material storage and movement : The function is mainly focused on moving stocked mat’l within stock or moved out from stock. 3.​ Shipping handling: Shipping operation cover services parts / Sample / Component return to supplier / machine / component to sub-contractor / others shipping -​ Incoming material control : material batch identification and traceability / Non-confirming material control / The measuring and test about key parameter of material / Inspection equipment calibration -​ In process control for product : Product batch identification and traceability / Non-confirming product control / The measuring , test and inspection about key parameter of product / Equipment calibration and maintance -​ Outgoing control for product: Batch release criteria / Rework instruction for batch release / ORT test , test equipment maintance / Out of Box audit / Line stop , shipping process d.​ Quality performance : Evaluate our quality performance and built robust quality system -​ Cost of non- quality : Fcous on improvement in cost reduction / prevention at all BCU manaufacturing site and non- quality is define following aspects: 1.​ Production missed in plants 2.​ Rework cost in plants 3. Warranty cost paid by plants 4. Abnormal airfreight costs 5. Scrap costs -​ Internal quality audit : The audit include PBE / ISO9000 / special audit by customer and the audit result should be the input to Management team . -​ Change control : Change control is define as aspects : 3.​ Document Change 4.​ Manufacturing Process Change. 5.​ Product change 6.​ Equipment Change
