PCB Warping: What are the dangers? PCB warpage is a serious issue that should be taken seriously by those in the PCB industry. For example: It will prevent the installation of SMT components and result in poor contact between electronic components and the solder joints. When all the electronic components are mounted, it is difficult […]

Vias make up an important part of a multi-layer PCB. The cost of drilling is usually 30-40% of the total cost. Every hole on the PCB is a via. Vias: Basic Concepts Vias are divided into two functional categories. One is for electrical connections, while the other is for fixing or positioning of devices. These […]

Flexible Printed Circuit Boards (PCBs) play a crucial role in modern electronic devices, catering to diverse application requirements with varied specifications. From double-layer computer flexible PCB boards to those designed for consumer electronics and single-layer medical applications, each possesses unique designs and applications.But if you have higher requirements, you wonder if they can be made into 4-layer […]

When processing and testing high-frequency PCB boards and high-frequency antennas, beginners often choose the incorrect high-frequency PCB, resulting in manufacturing unsatisfactory products. Let’s briefly what are high-frequency PCB boards and how to choose high-frequency PCB substrates.  Definition of high-frequency PCB board High-frequency circuit boards refer to special circuit boards with higher electromagnetic frequencies. They are […]

Electronic communication products have gone through many stages, including 1G, 2G and 3G. They are now moving to the fifth-generation communication product stage. 5G has better performance than 4G when it comes to peak rate, spectrum efficiency and time. There have been significant changes in PCBs and copper-clad materials. These have led to new requirements […]

The copper-clad laminate industry provides raw materials to the PCB industry. The copper-clad material is made of a flat plate by impregnating the electronic fiberglass cloth with resin adhesive, then drying, cutting and laminating them into plate material. Copper foil is applied to one or both sides and then hot-pressed. They are mainly used in […]

In high-speed and complicated circuit design, it is common to use more than four layers. How do you choose the right stack? This article analyses commonly used PCB stackups. Four-layer PCB stack-up design plan PCB stacking 1 optional: Top,GND2, PWR3, BOTTOM This is the standard 4-layer solution for the industry. Under the main device surface, […]

Bekalan kuasa memainkan peranan penting dalam aplikasi sistem. Reka bentuk PCB bekalan kuasa yang berkualiti boleh mengoptimumkan kecekapan kuasa, meredakan tekanan pelesapan haba dan mengurangkan pelepasan hingar untuk meningkatkan ketepatan dan kestabilan dalam kuasa luar. Pada masa ini, banyak aplikasi produk seperti perindustrian, automotif, komunikasi dan pengguna telah menuntut penyelesaian kecil; akibatnya, pengecilan […]

Hari ini, Eashub akan berkongsi beberapa petua dan petua untuk reka bentuk PCB berkuasa tinggi. Apakah PCB berkuasa tinggi? PCB Berkuasa Tinggi ialah papan bercetak yang diperbuat daripada tembaga berat. PCB berkuasa tinggi boleh mengendalikan kadar arus yang lebih tinggi, menahan suhu dalam tempoh yang lama, dan menyediakan sambungan yang kuat. Ciri PCB Kuasa Tinggi Suhu boleh menjejaskan reka bentuk […]
