Beijing: Leading PCB makers HTD circuits has announced a new range of Rigid PCBs. According to the MD, the market for rigid PCB is expanding fast and high-end manufacturers have to offer the best product that satisfies all parameters.
According to the MD, manufacturing of PCBs involves complex processes and is dependent on the hi-tech processes. End-user industries are looking for smart suppliers who can balance cost efficiency and energy efficiency.
From design to manufacturing and after sales support, HTD Circuits have a highly customer centric approach with all processes highly automated.
He said the electronic schematic of the circuit has been designed by the Computer Aided Design (CAD) software and the prototypes are planned with Computer Aided Manufacturing (CAM) software used by engineers to produce the PCB prototype.
After the PCB prototype is designed, the material of the printed circuit board is decided among the different PCB materials.
They can be one of the following --Alumina, Arlon, Bakelite, CEM1, CEM5, Ceramic, FR1, FR4, FR4 High Temperature, GeTek, Nelco, Polyimide, and Rogers.
After the material is selected, a coating of copper is applied to the entire board and the circuit layout will be printed on the board using a photosensitive process. The photo engraving process will be used as part of the circuit layout and result copper creates traces of the PCB circuit.
A mechanical milling process is used in connecting CNC machines to remove the unnecessary copper. The etch-resistant, silkscreen, printing process covers regions where traces exist.
During PCB fabrication, the PCB board will have copper traces without circuit components. For mounting components, holes are drilled at the points where the electrical and electronics parts are placed. The hole—drilling is done by lasers or special drills made of Tungsten Carbide. After holes are drilled, hollow rivets are inserted by an electroplating process creating an electrical connection between the layers.
The MD said the rigid PCBs will be in three types— single-layer, double-layer and multilayer PCBs. The double-layer PCBs have been made with complex circuits and doubled areas for conductor patterns.
Better innovation is achieved in ‘vias’, which are electrical ‘bridges’ functioning as holes filled with metals that conduct to all sides. International standards are maintained in the designing and manufacturing of new PCB series.
Quality levels of materials are in a constant update by stringent testing. The new PCBs will service end user industries like Telecommunication, Consumer Electronics, Automation Industries, Home Security, Automobiles, Computer Applications and Lighting industry.
