5G will bring great changes to the base station structure, and the consumption and unit price of 5G antenna PCB are expected to increase significantly. In the 4G era, a standard macro base station is mainly composed of three parts: base band unit (BBU), radio frequency processing unit (RRU) and antenna. Because the 10Gbps transmission…
With the rapid development of technology and application of electronic products, the technical requirements of electromagnetic shielding film are higher and higher. Flexible PCB tends to be high-frequency and high-speed, and the electromagnetic interference produced is more and more serious. Effective suppression of electromagnetic interference has become an important performance requirement of FPC products. At…
Copper clad laminate industry is in the middle reaches of the whole PCB industry chain, providing raw materials for PCB products. Copper clad laminate (CCL) is a kind of board-like material, which is made by drying, cutting and laminating the electronic glass fiber cloth or other reinforced materials with resin adhesive, covering one side or…
1 What is PCB impedance. In a circuit with resistance, inductance and capacitance, the resistance to alternating current is called impedance. At a certain frequency, the resistance of high frequency signal or electromagnetic wave in the transmission signal line of electronic devices relative to GND & VCC is called characteristic impedance, which is a vector sum…
In the market downturn and sinking, A-share "printed circuit board" plate is greatly sought after by capital, many shares have reached recent highs. Product price increase is the direct "fuse" of the "printed circuit board" plate explosion, and the leading companies in the printed circuit board industry will usher in greater development opportunities. …
Automotive wireless charging PCB is mainly used in wireless charging technology, which is derived from wireless power transmission technology. Wireless power transmission is also called wireless energy transmission or wireless energy transmission, mainly through electromagnetic induction, electromagnetic resonance, radio frequency, microwave, laser and other means to achieve non-contact power transmission. According to the different power…
Flexible PCBs (Printed Circuit Boards) offer many advantages, such as their ability to bend and conform to various shapes, but they also come with some disadvantages. Here are four disadvantages of flexible PCBs: Cost: Flexible PCBs are typically more expensive to manufacture than rigid PCBs. The materials used, such as flexible substrates and adhesives, are…
Characteristics of ceramic PCB products: 1. Substrate material: 96% alumina or beryllium oxide ceramics 2. Conductor material: silver, palladium, platinum and other alloys, the latest also has copper 3. Resistance paste: generally ruthenate series 4. Typical process: CAD > board making > printing > drying > sintering > resistance correction >…
I believe you are no stranger to IPC standard. Maybe you will hear customers say that our PCB is used in medical devices, and we require the product to meet the IPC class III standard. What is the IPC standard? In ipc-a-610c document, electronic products are divided into level 1, level 2 and level…
High frequency PCB is a special circuit board with high electromagnetic frequency. Generally speaking, high frequency can be defined as frequency above 1GHz. Its physical properties, precision, technical parameters requirements are very high. With the development of electronic equipment in the direction of high frequency, the application of high frequency circuit board is more and…
Taiwan Union Technology Corporation (TUC) was established in 1974. Its former name was Taiwan Union Glass Industrial Co., Ltd, mainly produced optical glass. In 1997, the company changed into producing Copper Clad Laminate (also called CCL) and Prepreg. In 2001, TUC started to provide Mass Lamination service for customers. In Dec., 2003, TUC was officially…
RO4360G2 laminates are 6.15 Dk, low loss, glass-reinforced,hydrocarbon ceramic-fi lled thermoset materials that provide the ideal balance of performance and processing ease. RO4360G2 laminates extend Rogers’ portfolio of high performance materials by providing customers with a product that is lead-free process capable and offers better rigidity for improved processability in multi-layer PCB board constructions, while…
RO4000® hydrocarbon ceramic laminates are designed to off er superior high frequency performance and low cost circuit fabrication. The result is a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes off ered at competitive prices. The selection of laminates typically available to designers is signifi cantly reduced once operational frequencies increase…
The PCB silk screen layer is the top layer in the PCB and is generally used for annotations. The correct principle for the layout of the characters on the silk screen layer is: “no ambiguity, stitches at a glance, beautiful and generous”. This is to facilitate PCB assembly and maintenance, etc., to print the required…
