Specifications for the manufacture of aluminum base PCB

The aluminum boards produced by Aluminium PCB manufacturers are mostly used for LED PCB lamps. What are the specifications for the production of aluminum base board in the production process? Aluminum boards produced by aluminum board manufacturers are often used in power devices, and the power density is large, so the copper foil is relatively thick. If a 3 oz or more copper foil is used, the etching process of the thick copper foil requires engineering line width compensation, otherwise, the line width after etching will be excessive. The surface of the aluminum boards produced by the aluminum board manufacturer must be protected with [...]

What is Ceramic PCB? Differences between PCB & Ceramic PCB

PCB or printed circuit boards are made by printing conductive pathways into a board that connects transistors, resistors, and integrated circuits. In the case of Ceramic printed circuit boards (Ceramic PCB), the conductive pathways are printed in ceramic baseboards. This essentially improves the performance quality of such circuit boards. The ceramic used in this case is not the typical ones that are utilized in floors; instead, it is a special kind of material called ‘fine ceramic.’ It is engineered with different chemical substances for specific uses. A ceramic printed circuit board is made of metal cores. Aluminum nitride boards [...]

WHAT IS CERAMIC PCB

WHAT IS CERAMIC PCB ? Dear All, What is ceramic PCB? HitechPCB works with ceramic PCB and varieties of PCB products. So, we have decided to share the definition and its uses with our readers. Ceramic PCB is a circuit board made with a ceramic base material. PCB is a short form of the printed circuit board. It is made of electronic ceramics that can be changed into many different shapes and sizes. For having high-temperature resistance and high electrical insulation performance, it is used in vastly in various fields that need better circuit boards. Some extra feature of it [...]

The role and difference of solder mask and solder paste layer

The impact of many projects on solder masks and solder layers is unclear. It is to open the window itself, but only provides the paste layer. There is no solder layer. Some board engineers don't look at the paste layer (note that this is used). This is a useless layer for the plant's engineers and can cause window leaks. The following is a brief introduction to their differences. The solder layer is used to control the area where the green oil (white oil) is not covered when the board is fabricated. For example, the position of the pad, [...]

AOI For Printed Circuit Board and PCB assemby China

Printed circuit board (PCB) and PCB assembly are substrates for assembling electronic components. The manufacturing quality of PCB directly affects the reliability of electronic products. Therefore, PCB are known as the "mother of the modern electronics industry." With the in-depth development of electronic assembly toward higher-density, smaller-sized PCB hybrid technology, relying only on traditional functional testing and manual visual inspection and inspection methods, it has been unable to meet the needs of modern PCB industry's large-scale production. At present, the primary yield of general PCB is still hovering between 60% and 70%. In order to reduce the number of defective [...]

Who Can Benefit From Turnkey PCB Assembly Services?

Advantages of Full Turnkey PCB Assembly Services and Who Can Benefit From Turnkey PCB Assembly Services? • Shorter Lead Time As a fundamental form of electronic assembly, PCB assembly primarily contains three phases: PCB fabrication, components procurement and PCB assembly. Traditionally, you should quote and confirm design files with sales and engineers working for your PCB manufacturer, then components distributors and finally PCB assemblers. Such series of quotations and confirmations just need your time spent in contacting with different partners. If those partners are from different countries, you have to overcome some problems such as time zone, communication habits etc. Full-turnkey [...]
