When designing a flexible circuit, it is important to understand the specific application of the flexible PCB board. Can it be used in a static or dynamic environment ? If the FPC board is to be placed in a static environment with little movement, the circuit design needs to have appropriate flexibility so that it can be easily installed in the product. Or, ...

1. High one-time initial cost: Since the flexible PCB is designed and manufactured for special applications, the initial circuit design, wiring and photographic masters require higher costs. Unless there is a special need to apply a flexible PCB, it is usually better not to use it in a small amount of application; 2. It is difficult to change and repair the ...

The biggest disadvantage of the rigid-flex PCB board is that the price of “rigid-flex PCB board” is more expensive, and it may be nearly double the original price of pure “FPC board + rigid PCB board”, but if the price of the connector and processing cost is deducted, the price may tend to be the same, and the detailed cost may have to be actuated to have a ...

Regarding Aluminum PCB or wrote as Aluminium PCB, there are different types of Aluminum which used for the laminate of Aluminium base pcb, the brief introduction as below. There are mainly three different types of metal aluminum base that commonly used, including 1000 series, 5000 series and 6000 series, the basic features of these three series aluminum base...

Generally speaking, the PCB aluminum substrate is composed of a circuit layer, a thermally conductive insulating layer and a metal base layer; it can be divided into three layers: Circuit layer: equivalent to the copper clad laminate of an ordinary PCB, the thickness of the circuit copper foil is 1 to 10 oz. The circuit layer (that is, copper foil) is usuall...

FR4 board is a code name for the grade of flame-retardant material. It represents a material specification that the resin material must be able to extinguish by itself after burning. It is not a material name, but a material grade. Therefore, there are many types of FR-4 grade materials used for pcb, but most of them are composite materials made of so-called...

Ordinary PCB board is mainly FR-4, which is laminated with epoxy resin and electronic grade glass cloth. Generally, traditional HDI PCB board uses backed copper foil on the outer surface, because laser drilling cannot penetrate the glass cloth, glass fiber-free backed copper foil is generally used. However, the current high-energy laser drilling machine can ...

PCB boards mainly divided into single-layer PCB boards and double-layer PCB boards, as well as multi-layer PCB boards. The most commonly used are single-layer PCB and double-layer PCB boards, and those with more than three layers are called multilayer PCB boards. For applications in different industries, there are different requirements for its shape, size, ...

The difference between a double-sided PCB board and a single-sided PCB board is that the single-sided PCB circuit is only on one side of the PCB board, while the double-sided PCB circuit can be distributed on both sides of the PCB board. Wiring of the double sided pcb board are being connected. In addition to the different production process between double-s...
