Layering and color changes in the gold-plated layer of a PCB (Printed Circuit Board) can be indicative of various issues or changes that may occur during the PCB manufacturing process or over time. Here are some reasons for layering and color changes in the gold-plated layer of a PCB: Oxidation: Gold is known for its…
Thick copper board requires special copper surface and thick copper surface, so there is a great height difference between copper surface and PP substrate. For example, if uniform filling and anti-welding between lines is required, poor process control will lead to bad phenomena such as ink floatation, false copper exposure or ink unevenness. In this…
With the development of science and technology, the application of PCB is more and more extensive. PCB is divided into single-sided PCB, double-sided PCB and multi-layer flexible PCB. Common multi-layer boards are generally 4-layer PCB or 6-layer PCB, complex multi-layer board. It can be used in dozens of layers and is widely used in consumer…
Recently, many customers asked the PCB Prototype what information to provide, and today we will give you a comprehensive answer. PCB Prototype is an early step in mass production. Only when proofing is accurate, can it be put into mass production. Therefore, it is especially important to provide accurate proofing files. So, do you know…
PCB processing belongs to the OEM customer’s OEM products. Different customers order different products, and there are few shared products. On the other hand, some customers may specify the use of a manufacturer’s substrate for quality considerations. Ink and so on, in order to achieve its quality and cost control requirements, so PCB processing prices…
After more than a year of hard work, our company finally passed the national high-tech enterprise certification.
It is well-known that PCBs are everywhere in the Shenzhen area of China. In our eyes, the PCB factory is a particularly cheap factory, but this board manufacturer is different. What is the truth? This board processing plant has a strict quality control system: Meets IPC-II or IPC-III standards Use SPC management chart for quality…
1. The outer frame (clamping edge) of the Custom PCB Manufacturing should adopt a closed-loop design to ensure that the PCB panel will not be deformed after being fixed on the fixture. 2. The width of the custom PCB fabrication is less than or equal to 260 mm (SIEMENS line) or less than or equal to…
The general custom PCB fabrication design process is as follows: pre-preparation → PCB structure design → PCB layout → wiring → wiring optimization and silk screen → network and DRC inspection and structural inspection → plate making Preliminary preparation This includes preparing component libraries and schematics. PCB structure design According to the determined board size and…
1. Custom PCB fabrication follows the layout principle of “first big, then small, first difficult and easy”, that is, important unit circuits and core components should be prioritized. 2. The layout should refer to the principle block diagram and arrange the main components according to the main signal flow direction of the board. 3. The arrangement…
MCPCB refers to Metallic PCB (MCPCB). That is, the original printed circuit board is attached to another metal with better heat conduction effect, which can improve the heat dissipation of the board layer. According to the type of application, it can be divided into three categories: (1) Universal aluminum-based copper clad laminate. The insulating layer…
A Metal-based Printed Circuit Board (MCPCB) is a type of printed circuit board that features a metal core, typically made of materials like aluminum or copper, serving as the base for electrical circuitry. MCPCBs are designed to address thermal management and heat dissipation issues in electronic devices and are widely used in various industries. Here’s…
The development of Metal Core Printed Circuit Boards (MCPCBs) has been driven by the need for efficient thermal management, high-performance, and reliability in electronic systems. MCPCBs, also known as Metal Core PCBs or Thermal PCBs, have gained popularity in various industries due to their excellent thermal conductivity and electrical insulation properties. Here’s an overview of…
PCB is an important electronic component, support for electronic components, and a carrier for electrical connection of electronic components. In the process of PCB manufacturing, blackening will occur. What are the main reasons for the blackening of the gold plated circuit board? 1. Electroplated nickel layer thickness control Gold plating on gold-plated circuit board is…
Polyester resin adhesive Polyester resin film thermoplastic adhesive is a high yield and low-cost material that can be rolled and processed. It can be made into heat-resistant material with copper sheet and conforms to the specification of ul-94vtm-0. It can’t pass drift tin test, the biggest using temperature is 110 ℃. Polyester resin adhesives are…
High Tg means high heat resistance. General Tg board for more than 130 degrees, high Tg PCB generally greater than 170 degrees, medium Tg is greater than 150 degrees. With the rapid development of electronic industry, especially electronic products represented by computer, the development towards high function and high multilayer requires higher heat resistance of…
