Why use ceramics for circuit boards?

Ceramic circuit boards are actually made of electronic ceramics material and can be made into various shapes. Among them, the ceramic circuit board has the most outstanding characteristics of high temperature resistance and high electrical insulation performance, and has the advantages of low dielectric constant and dielectric loss, high thermal conductivity, good chemical stability, and similar thermal expansion coefficient of the component, and Ceramic printed circuit boards are produced using LAM technology, a laser rapid activation metallization technology. Used in LED field, high power semiconductor module, semiconductor cooler, electronic heater, power control circuit, power mixing circuit, intelligent power component, high [...]

5 Questions to Ask PCB Manufacturer and electronic assembly services ltd

5 Questions to Ask PCB Manufacturer and electronic assembly services ltd With so many PCB manufacturers and PCB assembly suppliers to choose from, it's easy to feel overwhelmed with picking the right one. This may come as a surprise, but not all PCB manufacturers  and PCB assembly manufacturers are created equal.  In fact, by asking these questions before you choose a PCB manufacturer, you'll get to see firsthand how some manufacturers simply don't measure up to others. 1.How many years have you been in business? When it comes to manufacturing circuit boards, experience is everything. This question not only sheds light on a [...]

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 [...]

Printed Circuit Board industry accelerates transfer to China

The Printed Circuit Board industry moves eastward and the mainland is unique. The focus of the PCB industry is constantly shifting to the Asian region, and Asia's production capacity is further transferred to the mainland, forming a new industrial structure. With the continuous transfer of production capacity, mainland China has become the region with the highest PCB production capacity in the world.   Applications such as data centers will increase HDI board demand, and FPC will have broad prospects. Data centers are moving in the direction of high speed, high capacity, cloud computing and high performance, and construction demand is [...]

How to prevent your PCB from overheating

Green printed circuit board (PCB) Printed circuit board (PCB) materials are formulated to withstand a certain amount of heat. What happens when the temperatures rise beyond certain limits? Performance takes a nose dive, especially at higher frequencies. This is why cost-effective heat management is perhaps an engineer’s number-one priority. Of course, heat-tolerant PCB materials and carefully designed circuits can tolerate a certain amount of heat. First, the circuit designer should understand the different parameters of the materials’ behavior when temperatures rise.   Heat comes from various sources Circuit boards are assembled in increasing density to make smaller, lighter designs. A [...]

SMT assembly Processing / Patch Processing Basic Process Elements

The basic process elements of smt assembly processing / patch processing: Silk Screen (or Dispensing) --> Mounting --> (Curing) --> Reflow Soldering --> Cleaning --> Testing --> Rework Silk screen: Its function is to print solder paste or patch glue on the pad of PCB to prepare for soldering of components. The equipment used is a screen printing machine (screen printer), located at the forefront of the SMT production line. Dispensing: It is a glue that drops the glue to a fixed position on the PCB. Its main function is to fix the components to the PCB. The equipment used [...]

How to Decrease the PCB Assembly Cost

With improving technologies, the cost of every PCB assembly production is increasing. Profit margins are being raised. When you look for quality products for your application, the costs are likely to be even higher. But, you obviously want to reduce spending on your expenses, without compromising on the quality. Is that even possible? Electronics assembly manufacturing companies are always facing issues while attempting to cut down costs as the technology is constantly changing. Electronic devices are always evolving into more and more complex products, in order to meet consumer demands. This is why technology companies are evolving to find new [...]
