ISO 13485: This international standard applies to the quality management system of the medical device industry. It is designed to help medical device industry organizations ensure that their products meet customer and regulatory requirements.

ISO9001: The International Organization for Standardization standard provides a basis for the development of a quality management system (QMS) to help companies ensure that their products and services meet customer needs and continuously improve their business processes.

ISO 14001: This standard is used for the establishment and implementation of an environmental management system (EMS). It helps companies reduce adverse impacts on the environment while achieving economic benefits and fulfilling social responsibilities.


Quality Control and Standards


Based on 18 years of production experience, Wells Technology has summarized a set of strict internal control standards and MES systems, and adopts data management at every stage and every workstation in the manufacturing process; let the executive employees know the customer's requirements, production standards, and inspection specifications; let managers see real-time production records and production progress;

All our internal products are implemented according to industrial-grade quality standards; these quality control standards are stored in the data terminal at each workstation; the stored contents include program files, quality standard requirements, control processes, quality management manuals, SOP files, material inspection specifications, and job descriptions.

Our customer service team provides services to customers 24 hours a day and actively communicates with customers about their product manufacturing progress and any problems encountered during the production process. We also organize technical and design discussions between technical and engineering personnel from both sides. Ensure that our products meet customer requirements from supplier selection to production inspection to factory inspection and customer service.

In addition, our engineering team reviews project issues, solves difficulties in the project, and provides technical support to customers. After production, we summarize with customers to improve the space for product optimization; our commitment to internal control standards and engineer customer service has helped us gain a good reputation and a very trusting relationship with customers.



Quality Control

  Control station inspection items
  Incoming materials PCB:thickness, through-hole, pad, silk screen, warpage, circuit, solder mask, etc.;
Components:packaging, model, silk screen, quantity, measurement value, appearance, solder feet, temperature resistance, direction, etc.;
Structural parts:appearance, size, material, weight.
  StorageSensitive components:stored in a box with a relative humidity of 5%;
RoHS compliant:marked with RoHS or non-RoHS annotations after IQC processing;
Purpose of solder paste:sealed and stored in a refrigerator at 2-10℃, indicating the expiration date;Material identification card;
  Solder pasteBrand:choose famous solder paste brands, such as SMIC, Alpha, Vital
Rewarming:The rewarming time is about 3-4 hours to reach the ambient temperature of use (25±2℃)
Stir clockwise for 1-3 minutes with an automatic solder paste mixer
Use internationally renowned laser molds, with special attention to high-precision pads such as QFN, BGA, etc.
Control the thickness, area, and volume distribution of solder paste, and use 3D SPI detection

There are X-ray inspection equipment to check the welding quality of BGA components
IPQC first piece inspection, and the rest of the production will start after the test
  DIP weldingFurnace fixture inspection
Panel inspection
Wave soldering furnace temperature inspection
Welding effect inspection
IPQC first piece inspection, and the rest of the production will start after the test
  Assembly inspectionMaintain real-time communication with customers and translate all instruction requirements for engineers
Train and guide testers until they can understand all steps and operate independently
Share the test operation steps and test results with customers through video recording for confirmation and archiving
After the customer confirms the test results, continue to produce 100% of the products
Record the failure test results and inform how to solve these problems, and use them as a basis for future design improvements
  PackagingCarefully package the products with bubble bags, pearl cotton, antistatic bags, blister, custom boxes and other materials before transportation to prevent damage caused by static electricity and extrusion
