Delivery time

Customer R&D and market timetable fulfillment are critical to the success of the project. We regard this service concept as an important competitive advantage for PCB factories. Therefore, we value the realization of customer value. In the process of PCB manufacturing, it can provide an extremely flexible and changeable delivery cycle services. Fast sample prototypes service can be delivered as fast as 20 hours, Because our production engineers track every production step, hand-deliver product workstations, and prioritize internal file processing procedures, we can achieve rapid delivery on the premise of quality assurance. That is why we are able to become the most influential PCB manufacturer in the Pearl River Delta region.

PCB Quality control procedures

The whole process of IPQC (In-Process Quality Control) detection idea is one of our highlights. In the process of PCB manufacturing, IPQC with key points can avoid the opportunity cost of follow-up process caused by errors, facilitate early detection of problems and improvement, effectively reduce the scrap rate, pass the benefits of low production costs to customers and create sustainable value for customers. In addition, standard flying needle testing, test stand testing, AOI (automatic optical inspection) and other appearance testing form a closed-loop quality testing program combination, which is routinely implemented in our PCB factory.

Quality Control Procedure

We have accumulated rich experience in PCB manufacturing and have been at the forefront of PCB manufacturers in process improvement and quality control for decades.

1. Analysis and processing of process documents

Starting from receipt of production orders, process engineers will analyze whether the PCB design documents are correct, find problems and feedback them to customers for confirmation or modification in time, so as to establish the process mode, add corresponding markings on the edge of the decomposition documents, and mark the direction on the solder mask film.

2. Copper clad laminate storage, cutting, and drilling:

Select the best class A copper-clad laminate in the market, classify and store, grind edges and chamfers to prevent damage to the film and bring impurities to the plating cylinder to pollute the electroplating potion, accurately measure the tolerance of the drill bit, repeatedly check before drilling to avoid using the wrong bit, check whether the hole is offset and aperture after drilling. Correct or not.

Copper deposit and plating: The potting time in plating wire is checked to ensure the plating is in a stable level at all times, The PCB of each batch should be cross-sectioned to see whether the thickness and quality of copper layer in the hole meet the requirements under the electron microscope. Each batch of PCB chip reports is archived in the PCB factory for future reference.

3. PTH and Plating

In order to ensure that the plating is always at a stable level, each batch of circuit boards should be cross-sectioned, and the thickness and quality of copper layer in the hole should be checked under the electron microscope. Each batch of PCB slice report is archived in the PCB factory for reference.

4. Control of screen printing workshop in the darkroom

The thickness of printing ink is a very important process parameter of the circuit board. the time and the environment of mixing are strictly controlled.

5. Testing and improving

Test the flying needle of sample and small batch test board to ensure the electrical properties of circuit board meet the requirements and test the process control level of production process at the same time, The test bench of batch PCB can ensure 100 qualified electrical performance of factory PCB, and the drawing for the problem in the process of PCB processing can be easily improved.

How to Cooperate (PCB Process-Document List)

When you choose us as a supplier, you need to pass rigorous process control. Such as pre-audit of customer information to process evaluation.
