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.
As a primary testing technique in PCB assembly, AOI applies to fast and accurate inspection of errors or defects occurring in PCB assembly process, so that high quality of PCB assemblies can be ensured with no defect after their leaving assembly line. AOI is contributive to efficiency improvement because it is placed on SMT assembly line, just after reflow. As soon as some problems are inspected and reported by AOI equipment, engineers can instantly change corresponding parameters in the previous stages of the assembly line, so that remaining products will be correctly assembled. AOI can cover primarily come in soldering and components categories. In terms of soldering, AOI detect the defects ranged from open circuits, solder bridges, solder shorts, insufficient solder to excess solder. Component defects include lifted lead, missing components, misaligned or misplaced components.

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.
