Pcb prototype assembly manufacturer with atechpcb.com? The production of A-TECH complies with relevant laws and regulations. To ensure durability, our highly skilled QC professionals rigorously inspect the product. With many advantages, this product is highly reckoned in the market. We have high-quality pcb surface finish, including osp pcb, hasl pcb, immersion gold pcb, immersion silver pcb, peelable mask pcb, carbon pcb, immersion tin pcb and enig pcb. Peelable mask is one kind of temporary soldermask which use to protect some selected board areas during the surface finish or PCB assembly process to keep solder from flowing onto contacts, terminals or plated through holes.

Advantage of MCPCB: Some LEDs dissipate between 2-5W of heat and failures occur when the heat from a LED is not properly removed; a LED’s light output is reduced as well as degradation when the heat remains stagnant in the LED package. The purpose of a MCPCB is to efficiently remove the heat from all topical IC’s (not just LEDs). The aluminum base and thermally conductive dielectric layer act as bridges between the IC’s and heat sink. One single heat sink is mounted directly to the aluminum base eliminating the need for multiple heat sinks on top of the surface mounted components.

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.

In order to provide one-stop-services to customers, we can also provide FPC and Rigid-flex PCB Assembly service (also named SMT: Surface Mounting Technology). We can purchase all components from abroad or domestic market, and provide full products to you with short lead time. High Density Interconnects (HDI) board are defined as a board (PCB) with a higher wiring density per unit area than conventional printed circuit boards (PCB). They have finer lines and spaces (<100 µm), smaller vias (<150 µm) and capture pads (300, and higher connection pad density (>20 pads/cm2) than employed in conventional PCB technology. HDI board is used to reduce size and weight, as well as to enhance electrical performance.
