High quality printed circuit board assembly manufacturer
Printed circuit board provider right now? One of the key concepts in electronics is the printed circuit board or PCB. It’s so fundamental that people often forget to explain what a PCB is. This tutorial will breakdown what makes up a PCB and some of the common terms used in the PCB world. Printed circuit board is the most common name but may also be called “printed wiring boards” or “printed wiring cards”. Before the advent of the PCB circuits were constructed through a laborious process of point-to-point wiring. This led to frequent failures at wire junctions and short circuits when wire insulation began to age and crack. Discover extra info at best pcb.
Since beginning, as a printed circuit board (PCB) vendor in Asia, Best Technology is dedicating to be your best partner of advance, high-precision printed circuit boards, such as heavy copper boards, ultra thin PCB, mixed layers, high TG, HDI, high frequency (Rogers, Taconic), impedance controlled board, Metal Core PCB (MCPCB) such as Aluminum PCB, Copper PCB, and Ceramic PCB (conductor Copper, AgPd, Au, etc) and so on.
Metal Core PCB means the core (base) material for PCB is the metal, not the normal FR4/CEM1-3, etc. and currently the most common metal used for MCPCB manufacturer are Aluminum, Copper and steel alloy. Aluminum has good heat transferring and dissipation ability, but yet relatively cheaper; copper has even better performance but relatively more expensive, and steel can be divided into normal steel and stainless steel. It more rigid than both aluminum and copper, but thermal conductivity is lower than them too. People will choose their own base/core material according to their different application.
In order to provide one-stop-services to customers, we can also provide FPC and Rigid-flex PCB Assembly service (also named SMT: Surface Mounting Technology). We can purchase all components from abroad or domestic market, and provide full products to you with short lead time. High Density Interconnects (HDI) board are defined as a board (PCB) with a higher wiring density per unit area than conventional printed circuit boards (PCB). They have finer lines and spaces (<100 µm), smaller vias (<150 µm) and capture pads (300, and higher connection pad density (>20 pads/cm2) than employed in conventional PCB technology. HDI board is used to reduce size and weight, as well as to enhance electrical performance.
The design, as well as the manufacture of flexible PCBs, is a very nimble job. Seemingly minor errors such as two metal traces not being insulated on a high-voltage board, for example, can result in an arc leading to the destruction of the circuit. Errors in manufacturing can come by way of wrong selection of materials, improper design, and other such factors that can result in the capability of the flexible PCB to bend and take the required shape. If the PCB tends to fall from a height or any other external forces such as frequent plugging and unplugging of the PCB, it can cause damage to your PCB. Unreliable and faulty components can damage the board in many ways. One of them is the fact that they are unable to protect the PCB from overheating.
Flex PCB ( FPC ) is stands for Flexible Printed Circuits, or sometimes we just call it Flexible Circuits or Flex Circuits, which is the electronic component developed to allow electronic goods to become smaller and lighter, and it have been widely used from 1980s in USA & Europe, and then widely spread out around the world. Since flex circuits (flexible circuit) has excellent working efficiency and strong heat-resistance, it is widely used as a core component of all electronic goods such as cameras, computers and peripheral equipments, mobile phones, video & audio units, camcorders, printers, DVD, TFT LCD, satellite equipment, military equipments, and medical instruments. Anyway, Best Technology flex pcb manufacturer will provide OEM/ODM service.
Double sided flex circuits consists with double sided copper conductors and can be connected from both sides. It allows more complicated circuit designs, more components assembled. The major material used are copper foil, polyimide and coverlay. Adhesiveless stack up is popular for better dimensional stability, high temperature, thinner thickness. Dual access flexible circuit board refer to the flex circuit which can be accessed from both top and bottom side but only has only layer of conductor trace. Copper thickness 1OZ and coverlay 1mil, it similar with 1 layer FPC and opposite side FFC. There’re coverlay openings on both sides of flex circuit so that there’re solderable PAD on both top and bottom sides, that is similar with double sided FPC, but dual access flex circuit board has different stack up because of only one copper trace, so no plating process is need to make plated through hole (PTH) to connect between top and bottom side, and trace layout is much more simple. Capability: We are continued to improve our MCPCB, FR4 PCB & FPC & Ceramic PCB manufacturing level to get satisfactory result from customers and ourselves. See even more info at mcpcb.
