HDI PCBs are a type of multilayer PCB that utilizes advanced technologies to achieve higher circuit density and miniaturization. They incorporate microvias and high-density routing to accommodate complex and densely packed components.
Aluminum PCB, also known as Metal Core PCB, is a type of printed circuit board that uses an aluminum base material. It possesses unique characteristics and application advantages compared to traditional substrate materials such as FR-4. The structure of a
Aluminum PCB, also known as Metal Core PCB, is a type of printed circuit board that uses an aluminum base material. It possesses unique characteristics and application advantages compared to traditional substrate materials such as FR-4.
Multilayer PCB (Printed Circuit Board) refers to a type of PCB that consists of multiple layers of conductive traces and insulating material stacked together. Unlike single-layer or double-layer PCBs, which have only one or two layers of conductive materi
Heavy Copper PCB refers to a type of printed circuit board that features a significantly thicker copper layer compared to standard PCBs. The copper thickness in heavy copper PCBs typically ranges from 3 ounces (105 micrometers) to 20 ounces (700 micromete
Accuracy of design documents
The success of PCB production is related to the accuracy of the design file, so it is necessary to be as accurate as possible when designing the PCB board, and to verify and modify it many times.
Precision and quality of plate making
Plate making is the core link of PCB production, and its accuracy and quality directly affect the quality and stability of PCB board. Therefore, the plate making process requires fine operation and control to ensure the accuracy and quality of plate making.
Etching control
Etching is one of the key links in PCB production, and it is necessary to control the parameters of etching time, temperature, concentration and so on to avoid incomplete etching or excessive etching.
Quality of welding
Welding is one of the important links of PCB production, it is necessary to control the temperature, time, pressure and other parameters of welding to ensure the quality of welding and avoid problems such as weak welding or short circuit of the pad.
Thoroughness of cleaning
Cleaning is the last link in PCB production, it is necessary to ensure the thoroughness of cleaning, avoid leaving residue or water stains, affecting the quality and stability of the PCB board.
Perform safe operations
PCB production involves a variety of chemicals and equipment, and requires safe operation to ensure the safety and health of operators.
Customer service
A special customer service team contacts customer, offers quick response and provides return and refund service.
Delivery
Before delivery, the item number, customer code, quantity and consignee etc must be fully checked by the PQA.
Test of finish product
Open/short, visual inspection and physical testing.Flying probe,ICT,and functional testing.
Control in Manufacturing
The factory has advanced automatic production line which reduces manual damage to boards.
Pre-production Arrangement
The engineer checks the customer's design information, makes the production documents twice and is confirmed by the customer.
