Quality Concept

PCB manufacturers face a series of market challenges, such as rapidly changing products, increasingly complex global supply chains and uncertain demand. In order to meet customers' response to the market in the ever-changing environment, Huihe Circuits continue to improve and optimize the production process, PCB circuit board product quality and after-sales service, to provide customers with an extraordinary customer experience. For this reason, the quality concept of Huihe Circuits is: strict management, continuous improvement, excellent quality and customer satisfaction. 

  •  Understand the expectations and needs of each customer.

  •  Continue to create and provide customers with new product value and services.

  •  Set quality goals from the customer's point of view, and then measure internal operations against those goals.

  •  To solve customer problems in a timely manner, Huihe Circuits can prevent problems from happening again by truly understanding the root causes and eliminating them.

  • The company has established a first-class quality management system to continuously improve the continuity and effectiveness of system management.

  •  Huihe Circuits has passed a series of ISO9001/ISO13485/IATF16949/OHSAS18001 system certification. 

Quality Management Objectives

Considering the competitive nature of the electronics industry and the selective diversification of end consumers, the demand for high-quality electronic products does put great pressure on electronic manufacturers. Therefore, the Huihe Circuits puts forward the following PCB board quality management objectives:

1. Timely delivery rate of order ≥ 95%.

2. The qualified rate of finished product ex-factory inspection is 100%.

3. Customer satisfaction ≥ 90 points. 

  •  Reduce the cost and risk of customers in the supply chain.

  •  Provide customers with extraordinary customer quality experience.

  •  Reduce the quality risks caused by non-conformities in the manufacturing process.

  •  Identify and eliminate operational risks.

  •  Ensure compliance with laws and regulations.  



PCB Quality Assurance

PCB testing should be considered at multiple stages of the PCB board product life cycle, including the design / layout, manufacturing, and assembly phases. Whether it is a simple bare board or an assembly board for continuity and network list testing, testing is strongly recommended. The Huihe Circuits provides extensive and comprehensive PCB testing and inspection for each PCB circuit board. 

1. DFM/ manufacturability design, test optimization data.

2. Visual inspection.

3. Automatic optical / AOI inspection.

4. Impedance test.

5. Performance testing.

6. Gold image microsection examination.

7. Electrical test.

8. High voltage / Hi Pot test

After Sales Service

The salesman receives the customer feedback notice (phone, fax, email, etc.), immediately records the customer feedback in detail, and determines the batch, quantity, defect rate, time, place, sales volume, etc.

The salesman will record the details in the customer complaint information statement form and send it to the quality department for analysis. 

Problem Product Analysis

1. After receiving the feedback from customers, the quality department confirms with the relevant departments the quantity of raw materials, semi-finished products and finished products in the warehouse, stops the production and transportation of products with similar bad problems, and carries out the procedures for dealing with non-conforming products in accordance with the control measures.

2. The quality department, together with the production department, engineering department, customer service department and other relevant departments, carries out experimental analysis, testing, dissection and comprehensive comparison of the products of the same batch of products (or samples provided by customers). Analyze the material, structure, process and testing capability of the product, and find out the real reason, which are recorded in the 8D / 4D report. 

After-Sales Procedure

1. The quality department confirms the quality of the returned products and specifies the handling method of the returned products. If the rejected product is dealt with in accordance with the "nonconforming product control procedure", the quality department will record the monthly return processing on the "return processing tracking form".

2. Defective returned products shall be reprocessed by the production department.

3. Non-rework treatment shall be determined by the quality department as waste treatment or degradation treatment.

4. The quality department will lead the relevant departments to inspect and deal with the unqualified products in a timely manner.

5. The related expenses arising from the return or exchange of goods shall be determined by the salesperson and the customer through consultation. 

After-Sales Tracking

1. Short-term effectiveness: if there are no continuous abnormal batches after the improvement and no bad feedback from the customer is received, the improvement measures are considered to be effective.

2. Long-term effectiveness: investigate and evaluate according to the customer satisfaction Management procedure. If you are not satisfied with the quality, service and related customers, you should follow the corrective and preventive control procedures. 

After-Sale Time

Feedback (written, telephone or email) should be provided within 2 working days after receiving the customer complaint.

Record Preservation

Summarize customer complaints in the customer complaint Analysis report every month and report them at the monthly quality meeting. Statistical technology is used to analyze the current situation and trend of customer complaints.
