SMT Assembly

LUPHITOUCH has our PCB assembly factory for SMT/SMD assembly (also including Flexible Printed Circuit assembly and silver printed PET circuit assembly), through-hole and mixed technology PCB assemblies. BGA down to 0.25mm pitch, 0201 component placements and leadless devices assembly can also be available. We also do the integrated assemblies and turnkey assemblies for our customers. From the product design, drawings making, tool making, electronics components sourcing and suggestion, plastic, metal, rubber, membrane keypad, wire harness, LCD, touchscreen etc. sourcing and assembly, final testing, and shipping. Our own PCBA factory is certified by ISO9001 and ISO14001. Our PCBA manufacturing service focus on the prototypes to midvolume production.    1) Rigid PCB Assembly (PCBA): For the rigid printed circuit board(PCB), the materials are usually are FR-4、High TG FR4、Halogen Free Material, Rogers、Arlon、PTFE、Taconic、Isola, Ceramics, Aluminum, Copper base etc. It is rigid and have very good support feature. Due to it is rigid so it also couldn't be bended for some special application. Also due to its rigid capability, it has best reliability and also easy for the components assembly. The rigid PCB can be single layer and multilayers. 2) Flex Copper Circuit Board Assembly (FPCA);The material material for FPC is the copper foil. FPC also has good relaibility. It is flexible and thin, then it can be used many special area. There are different types of FPCs in the market. They are single layer, double layers, single side double access, single side plus single side, multi-layers, COF(clip-on-film) and flex-rigid circuit board. To assemble components on FPC is much difficult than on rigid PCB. So in the market we usually see that only small quantity components assembled on FPC. The components assembled FPC should try to avoid the bad bending, otherwise the soldering can be easily damaged and then cause the product lost function. So this is also decided that usually couldn't assemble too much components on FPC if the application needs bend the circuit board. 3) Silver Printed PET Foil Circuit Assembly (PETA);For the silver printed circuit board, the material is usually the Polyester(PET), and in nowadays also can print circuit on a kind of special paper. PET has the following good advantages which caused its application in printing electronics industry fastly:     3.1) Optically brilliant, clear appearance;   3.2) Unequaled mechanical strength and toughness;    3.3) Good flatness and coefficient of friction (COF)   3.4) Tear-resistant and puncture-resistant characteristics   3.5) Wide range of thicknesses-as thin as 1 micron up to 350 micron   3.6) Excellent dimensional stability over a wide range of temperatures    3.7) Very good resistance to most common solvents, moisture, oil, and grease    3.8) Excellent barrier against a wide range of gases   3.9) Low cost;
