Some Information about the Progress of SMT Technologies by Linked Electronics, the PCB manufacture in China
During the 1970s and 1980s the level of automation started to rise for electronic PCB assembly for PCB boards used in a variety of equipment. The use of traditional components with leads did not prove easy for PCB assembly. Resistors and capacitors needed to have their leads pre-formed so that they would fit through holes, and even integrated circuits needed to have their leads set to exactly the right pitch so that they could be placed through the holes easily. This approach always proved difficult as leads often missed the holes as tolerances required to ensure they fitted exactly through the holes were very tight. As a result operator intervention was frequently required to resolve the issues of components not fitting properly and stopping the machines. This slowed down the PCB assembly process and considerably increased costs. For PCB assembly there is actually no need for the component leads to pass through the board. Instead it is quite adequate for components to be soldered directly to the board. As a result, surface mount technology, SMT was born, and the use of SMT components rose very rapidly as their advantages were seen and realised. Concept of surface mount technology - this shows a typical SMT resistor or SMT capacitor mounted on a board. Concept of surface mount technology: a typical passive component Today surface mount technology is the main technology used for PCB assembly within electronics manufacturing. SMT components are able to be made very small, and may types are used in their billions, particularly SMT capacitors and SMT resistors.

Quality Control at Linked Electronics, the PCB Assembly Service Manufacture in China
At Linked Electronics, we choose branding raw materials including UniOhm, Samsung, Yageo resistor and capacitors, TI, NXP, CJ, Toshiba, Fairchild, ST, Qualcomm, Micron, Infineon IC are bought from Mouser, Digikey, Arrow and other platforms. Quality and lead time can be ensured because we have our purchasing office in Hongkong.
We have AOI and X-ray inspection machines which will be able to detect appearance of welding spot and ensure materials pasted by enough solder. What’s more, Linked Electronics can offer services of burning programming codes, in-circuit test, burn-in to reach high quality requirements. At delivery stage, we use anti-static electricity bubble bag and plastic bag outside to pack every printed circuit board, then place them into solid cartons with full protection. In this way, all PCBs are packed in a safe condition during air, ocean, vehicle transportation.
