High quality pcb manufacturer in China? Peelable mask are applied by screen-printing, act as in-process protection and are removed after processing at the assembler. Because the fabricator can apply the mask in any design, they can create one fluid piece which will allow the customer to peel the entire design off in one pull. Peelable mask provides protection in soldering processes like wave soldering, reflow soldering or hot air solder leveling(HASL). Rebiable, time-saving and cost-saving in their application, they have long surpassed manual masking with heat-resistant tapes. See more info at pcb manufacturer China.
The main difference between a FR4 board and MCPCB is the thermal conductivity dielectric material in the MCPCB. This acts as a thermal bridge between the IC components and metal backing plate. Heat is conducted from the package through the metal core to an additional heat sink. On the FR4 board the heat remains stagnant if not transferred by a topical heatsink. According to lab testing a MCPCB with a 1W LED remained near an ambient of 25C, while the same 1W LED on a FR4 board reached 12C over ambient. LED PCB always be produced with Aluminum core, but sometimes steel core PCB also be used.
Our automated X-Ray inspection systems are able to monitor a variety of aspects of a printed circuit board in assembly production. The inspection is done after the soldering process to monitor defects in soldering quality. Our equipment is able to “see” solder joints that are under packages such as BGA, CSP and FLIP chips where the solder joints are hidden. This allows us to verify that the assembly is done correctly. The defects and other information detected by the inspection system can be quickly analyzed and the process altered to reduce the defects and improve the quality of the final products. In this way not only are actual faults detectd, but the process can be altered to reduce the fault levels on the boards coming through. Use of this equipment allows us to ensure that the highest standards are maintained in our assembly.

Flat Flexible Cable (FFC) is made of PET insulation material and extremely thin tinned flat copper wire, it has free bending and folding, thin thickness, small size, simple connection, easy to solve electromagnetic shielding (EMI). Common ffc cables’ specifications are 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 1.5mm, 2.0mm, 2.54mm and other various pitches to match different types of connectors. Rigid-flex PCB is a circuit board combined of rigid board and flexible circuit, from 2 layer to 50 layers, has the advantage of rigidness, flatness, flexibility and bendability. You can see advantage of rigid flex circuit such as design high density, less components need, less space, and stack up. Welcome to visit our website for rigid flex pcb manufacturers.
