Quality Management

Sunthone, ISO9001 certified one-stop PCB manufacture, operates under robust North American 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.

1.Evaluation and Audit of our Suppliers

Suppliers must be evaluated before approval by Sunthone's supplier evaluation team. In addition, Sunthone will appraise and rank every supplier once a year to guarantee the suppliers provide the quality materials meeting Sunthone 's requirements.

2.Contract Review

Before accepting an order, Sunthone shall review and verify customer's requirements to make sure that Sunthone has the capability to satisfy customers' requirements including specification, delivery and other demands.

3.Preparation, Review and Control of Manufacturing Instruction

Sunthone will evaluate all the requirements after receiving the customers' design d ata 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 Sunthone's real manufacturing process and technologies. Sunthone makes ways to guarantee that the manufacturing documentation is right and valid.

4.Incoming Control IQC

In Sunthone, all materials must be verified and approved before going to the warehouse. Sunthone establishes strict verifying procedures and working instructions to control the incoming. Furthermore, Sunthone owns various precise inspection instruments and equipment to guarantee the capability to rightly judge whether the verified material is good or not. Sunthone applies a computer system to manage materials, which guarantees that materials are used by first-in-first-out.

5.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 equipments 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.

6.Final Control and Inspection

In Sunthone, all PCBs must go through the open and short test as well as visual inspection after passed the relative physical tests. Sunthone owns various advanced test equipments to test the finished PCB.

7.Outgoing Audit and Approval

Sunthone sets 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.

8.Customer Service

Sunthone sets up a professional customer service team to proactively communicate with customers and timely deal with the customers' feedback. Sunthone is highly concerned about customers' needs and periodically surveys customers to learn about their requirements.
