Below are about our quality control procedures:
Supplier Evaluation And Audit
Suppliers must be evaluated before approval by Yingstar's supplier evaluation team. In addition, Yingstar will appraise and rank every supplier once a year to guarantee the suppliers provide the quality materials meeting Yingstar's requirements. Furthermore, Yingstar continuously develops suppliers and promotes them to improve their quality and environment management basing on the systems of ISO9001.
Before accepting an order, our engineering teams will check all the details of this project and make sure we have the capabilities to handle it.
Preparation, Review And Control Of Manufacturing Instruction
Before processing an order, our engineering teams will check all details of this project, and if any issues detected, we will report them to customers and give them our solutions or suggestions.Once our solutions or suggestions are approved by our customer, we will start to process this order.
Incoming Control IQC
All materials must be verified and approved when going to the warehouse. Yingstar establishes strict verifying procedures and working instructions to control the incoming electronic materials. Furthermore, Yingstar owns various precise inspection instruments and equipment to guarantee the capability to rightly judge whether the verified material is good or not.
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.
Strict PCBA tests
We perform multiple quality assurance procedures before shipping out any of our board to guarantee our quality.
These testing methods include:
· Visual Inspection,
· X-Ray Inspection,
· AOI Inspection(Automated Optical Inspector),
· ICT test (In-circuit test), and
· Functional test (test guide need to be supplied).
