A-TECH China immersion silver pcb finish company at discount

Company Advantages
1. A-TECH enig pcb finish goes through the standard production process. It will be designed with CAD technology, machined (cutting, molding, and finishing), trimmed in terms of edges and surfaces. It has passed AOI which ensures there will be no errors or welding defects
2. One of the customers said that this product is durable enough to stand up numerous times of switch on/off without causing any problems. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
3. with the characteristics of enig pcb finish , immersion silver pcb finish can complete meet the production need. It can be printed with numbers, names, data codes, logos, or other specific information
4. immersion silver pcb finish has some virtues such as enig pcb finish and so on, so it has been become a developing trend gradually. The product has the performance of great stability

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.
