Company Advantages
1. The production process of A-TECH tin plating pcb involves coagulation, a process that curdles or thickens the polyisoprene into a mass. This process is accomplished by adding an acid. It totally conforms to the UL Flame Rating of 94V-0
2. A-TECH CIRCUITS Co., Ltd. has rich series of products and project portfolios and a comprehensive operating network. The product has the performance of great stability
3. osp pcb also has other highly marketable qualities such as tin plating pcb . Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
4. At the same time, it also guarantees the upgrade and maintaince of osp pcb . With a compact design, it is space-saving
5. osp pcb is regarded as one of the most promising tin plating pcb to osp pcb finish . It has passed AOI which ensures there will be no errors or welding defects


Carbon Ink is typically used to create a protective contact surface for switches, sometimes few copper elements or patterns of the PCB board are used for keyboard contacts, LCD contacts and jumpers etc, to do this it’s usable to print some conductive/resistive carbon ink over those copper part, which normally are SMD pads or fingers or other typical contact patterns.

Carbon Ink printing process is screen printing like silk screen process, the carbon ink is printed in the specified location of the PCB, after oven cured and tested, formed a carbon film which with certain resistance to instead of the original resistance components. The difference is that silkscreen is only played a welding role but carbon ink has conductive performance.

The typical thickness of carbon ink is 10-50um, because the carbon ink has good electrical conductivity, so the carbon printed on the finished PCB should have a certain gap to ensure that no short circuits, usually require the min 8mil gap for Hoz copper and min 12mil gap for 1-3oz copper, and the minimum carbon line width is 12mil.

A-TECH is a capable PCB manufacturer to offer Carbon ink process, we require the data files to clearly indicate on which side of the PCB carbon is to be applied and the carbon areas must be properly indicated on specific layers with proper file naming.
