ProtoPCB, PCB Manufacturing house, operates under best in class operating procedures for all quality and process controls. These procedures assure that our product satisfies customer requirements in every stage and aspect of a development; from the selection of the suppliers to WIP inspection, and through to outgoing inspection and customer service. Here are just a few specific examples:
Evaluation And Audit Of our Suppliers
Suppliers must be evaluated before approval by ProtoPCB’s supplier evaluation team. In addition, ProtoPCBwill appraise and rank every supplier once a year to guarantee the suppliers provide the quality materials meeting ProtoPCB’s requirements. Furthermore, ProtoPCBcontinuously develops suppliers and promotes them to improve their quality and environment management.
Contract Review
Before accepting an order, ProtoPCBshall review and verify customer’s requirements to make sure that ProtoPCBhas the capability to satisfy customers’ requirements including specification, delivery and other demands.
Preparation, Review And Control Of Manufacturing Instruction
ProtoPCBwill evaluate all the requirements after receiving the customers’ design data and related document. Then, transform the design datum into manufacturing datum by CAM. Finally, a MI which incorporates the manufacturing datum will be formulated according to ProtoPCB’s real manufacturing process and technologies. MI must be reviewed after preparation by independent engineers. Before the MI is issued, it must be reviewed by QA engineers and get approved. Drilling and routing datum must be confirmed by first article inspection before issued. In a word, ProtoPCBmakes ways to guarantee that the manufacturing documentation is right and valid.
Incoming Control IQC
In ProtoPCB, all materials must be verified and approved before going to the warehouse. ProtoPCBestablishes strict verifying procedures and working instructions to control the incoming. Furthermore, ProtoPCBowns various precise inspection instruments and equipment to guarantee the capability to rightly judge whether the verified material is good or not. ProtoPCBapplies a computer system to manage materials, which guarantees that materials are used by first-in-first-out. When one material gets close to expiry date, the system will issue a warning, which ensures that materials are used up before expiry or verified before use.
Process Controls Of Fabrication
Right manufacturing instruction (MI), total equipment management and maintenance, strict WIP inspection and monitoring as well as working instructions, all these make the whole production process totally controlled. Various precise inspection equipment’s including the AOI inspection system as well as perfect WIP inspection instructions and control plan, all these guarantee that semi-products and final products, all reach the requirements of customers’ spec.
Final Control And Inspection
In ProtoPCB, all PCBs must go through the open and short test as well as visual inspection after passed the relative physical tests. ProtoPCBowns various advanced test equipments including AOI Testing, X-ray inspection and In-Circuit Testing for finished PCB assembly.
Outgoing Audit And Approval
ProtoPCBsets up a special function, FQA to inspect the products according to the customer’s spec and requirements by sampling. Products must be approved before packing. Before delivered, FQA must 100% audit every shipment for the fabrication part number, customer’s part number, quantity, destination address and packing list etc.
Customer Service
ProtoPCBsets up a professional customer service team to proactively communicate with customers and timely deal with the customers’ feedback. If necessary, they will cooperate with the customers to solve the relative problems on the customers’ site. ProtoPCBis highly concerned about customers’ needs and periodically surveys customers to learn about their requirements.
