Pcb supplier 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. Read additional information on pcb prototype assembly.
Sometimes people will use abbreviation MCPCB, instead of the full name as Metal Core PCB, or Metal Core Printed Circuit Board. And also used different word refers the core/base, so you will also see different name of Metal Core PCB, such as Metal PCB, Metal Base PCB, Metal Backed PCB, Metal Clad PCB and Metal Core Board and so on. MCPCBs are used instead of traditional FR4 or CEM3 PCBs because of the ability to efficiently dissipate heat away from the components. This is achieved by using a Thermally Conductive Dielectric Layer.
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.
A-TECH CIRCUITS was founded in 2003, which was a UL(E357001), ISO9001:2015, ISO14001:2015, IATF16949:2016 and RoHS certificated (printed circuit boards) PCB manufacturer and PCB assembly manufacturer with 15 years’ experience, the headquarter and sales office was located in ShenZhen city of China, the manufacturing facilities was located in HuiZhou city where is about 150KM from ShenZhen city.

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.
