PCB Manufacturing

Not only provides one-stop PCBA service, but also provides customers with PCB circuit boards of various materials, special processes and surface treatments. Each piece of PCB is made of high-quality raw materials and undergoes strict testing. Each production link is specially inspected by QC. The operator self-inspects and QA sampling checks the product layer by layer. The factory products can pass UL certification, CE, MIN standards, ISO-9001 quality System certification, EU SGS lead-free product certification.

The company has an experienced professional process team and quality control system, which can provide various special process PCB boards, such as: impedance board special ink (matte ink, purple, etc.) blind buried hole super long, ultra-thin board countersunk hole OSP process Thick copper plate, bare copper plate, high frequency and high speed HDI, etc. At the same time, it can also meet the needs of customers in various fields, and provide a variety of materials: FR4 board, Teflon board, ceramic board, halogen-free board, high TG board, mixed pressure board, ultra-thin board, ultra-thick board. The refined production process provides a variety of surface treatment processes, such as: OSP, lead-free spray tin, immersion gold, immersion tin, immersion silver, electric gold, etc. Alto promises that the quality of all products conforms to industry standards before leaving the factory.

Raw material guarantee:

arantee
[HASL] The function is to prevent the oxidation of the bare copper surface and maintain solderability. As a common form of surface coating, the quality of the sprayed tin directly affects the quality and solderability of the subsequent production.
arantee
[Immersion gold plate]The process is to deposit stable color, good brightness, flat coating and good solderability on the surface of the printed circuit. Nickel-gold coating is divided into: Pre-treatment (degreasing/micro-etching/activation/post-dipping); Post-treatment (Immersion Nickel/Immersion Gold).
[Gold finger] The process is to cover a thin nickel-gold layer on the copper surface through electrochemical redox reaction. Advantages: wear resistance, anti-oxidation, low resistance, thick plating control: 0.25-1.5um.

Quality control:

AOI automatic optical inspection
AOI automatic optical inspection is based on the principle of optics and comprehensively adopts various technologies such as image analysis, computer and automatic control to automatically detect and process PCB defects encountered in production, which can efficiently and accurately screen out defective products and avoid problems. Defective PCBs flow to the client or the next process.
Flying probe test
Flying probe test, the test probe moves quickly point by point on the PCB to complete the test. Generally, the capacitance method is used for testing. When the measured capacitance is not within the qualified range, the resistance method is used for accurate confirmation. Each test probe is controlled by a precise transmission system, and the position accuracy can reach 0.01mm, which can test circuit boards with higher density and smaller PAD.
Manual inspection
Manual inspection, the company has a relatively complete quality management system, and professional inspection personnel are equipped in each production link, from IQC inspection of raw materials, IPQC inspection of the production process, to OQC inspection of shipments, to check the quality of each PCB layer by layer , which can greatly reduce appearance defects, such as blistering, distortion, dirt and other problems.
X-RAY testing equipment
X-RAY testing equipment uses the contrast effect images generated by the changes in light intensity of X-Ray penetrating materials of different densities to detect the internal structure of ultra-fine pitch and ultra-high density PCB circuit boards, and thus can be used without damaging the PCB. In the case of circuit boards, observe areas inside the PCB where there may be problems, such as bridging, missing chips, misalignment, open circuits, etc.
Two-dimensional measurement
Two-dimensional measurement, using a two-dimensional image measuring instrument to measure the hole position, length and width, position and other dimensions. Since the PCB is a small, thin and soft type of product, the contact measurement is easy to produce deformation, resulting in inaccurate measurement. The two-dimensional image measuring instrument has become the best high-precision dimensional measuring instrument.
FCT/ICT test
FCT/ICT test, according to the PCB test plan provided by the customer, including test points, procedures, PCB test stand, ICT/FCT fixture, test steps, in order to simulate the input and output of the PCB circuit, and measure whether the value meets the standard, etc.
