  • PCBA preservation and shelf life
    1. Environment: A wet and dusty environment accelerates oxidation and dirt accumulation, shortening shelf life. Storage in a dry, dust-free area at a constant temperature of 25°C is recommended. 2. Reliability of Components: The durability of the components significantly influences the shelf life of the PCBA. High-quality materials and processes enhance resistance to harsh conditions and improve antioxidant capacity. 3. PCB Material and Surface Treatment: While PCB materials are generally stable, surface oxidation is a concern. Effective surface treatment can extend the shelf life of PCBA. 4. Operating Load: The load during operation is critical; high-frequency and high-load conditions can cause oxidation and potential circuit failures. It is advisable to operate PCBA within mid-range parameters to minimize stress and enhance shelf life. Read More
  • 10 important features of high reliability circuit boards
    For a PCB to deliver reliable performance, both in manufacturing and assembly as well as in actual use, quality and strict adherence to standards are vital. While higher initial costs are required for long-lasting PCBs, the long-term value outweighs these costs. Key reliability features include a hole wall copper thickness of 25μm to prevent electrical failures, the use of known high-quality base materials to ensure mechanical and electrical properties, compliance with IPC cleanliness and soldermask requirements to prevent residue and short-circuiting, and strict control over surface treatment lifetimes to avoid issues like moisture intrusion and delamination. Avoiding repairs on broken lines, defining tolerance limits for mechanical aspects, ensuring high-quality plugged holes, and not using X-out panels further contribute to improving PCB assembly efficiency and reducing failure risks during actual use.

  • Factors that affect prototype PCB price
    The pricing of prototype PCBs is influenced by several technical factors, with other business-related factors like location and quality excluded. Major factors affecting PCB costs include expedited delivery fees, especially for single or double-sided boards; flying probe testing for complex designs or larger PCBs; surface treatment costs, with expensive materials like gold and nickel adding to the price; soldermask costs, where special colors increase expenses; board size, which consumes more substrate and raises the price; and fixed costs like engineering fees and film costs, which increase with the number of PCB layers.

  • Circuit board process mainly divided in to 7 steps
    The production process of a printed circuit board (PCB) can be divided into seven main steps. First, a PCB drawing is prepared and printed on transfer paper, selecting the best print for production. Next, a copper-clad laminate (CCL) is cut to the appropriate size. The CCL is then pretreated by polishing the surface to remove any oxide layer. The circuit design is transferred onto the CCL using a heat transfer machine, typically set between 160-200 degrees Celsius. The board is then etched to remove the exposed copper using a solution of concentrated hydrochloric acid, hydrogen peroxide, and water. After etching, holes are drilled for electronic components based on their pin sizes. Finally, the surface of the PCB is treated by removing toner, polishing, and applying a rosin coating to protect the board. This step-by-step process, as described by SysPCB, a Shenzhen-based PCB manufacturer, ensures the quality and readiness of the PCB for further assembly and use. Read More
  • Files need for PCB quotation
    For PCB quotations, while simple single-sided or double-sided PCBs can be roughly estimated using PDF or JPG files, it is challenging to provide accurate quotes for complex multilayer PCBs with more than four layers. PDF and JPG formats are insufficient for PCB fabrication, as only PCB format files or Gerber files are suitable. If PCB files are unavailable, PCB samples can be used to generate Gerber files. PCB designs should be created using common software like Protel DXP, Powerpcb, or PADS, and the files must be in formats such as PCB, ODB, Gerber, or DWG. Additionally, specifications like board thickness, copper thickness, solder mask color, and surface treatment must be provided for accurate quotations or production. It's also important to verify the manufacturing capacity of the PCB provider to avoid potential production issues. Read More
