A-TECH hot-sale enig pcb cheapest factory price at discount

Company Advantages
1. A-TECH enig pcb has to go through the following manufacturing steps: CAD design, project approval, materials selection, cutting, parts machining, drying, grinding, painting, varnishing, and assembly. It stands out for its impact endurance performance
2. The product is able to fit the natural shape of people's feet. So wearing this product will not easily cause a sore blister at the bottom of people's feet. It is offered with low dielectric loss
3. The product stands out for its dimensional stability. It can maintain the original pleating and don't easily shrink or elongated.
4. The product features accurate specifications. It usually has tight tolerances in order to match up to other parts or assembly. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
5. The product features a long service life. The light-emitting element adopts a high-composite material to minimize the aging effect that caused by long-time high-temperature working. It has low water absorptivity in the damp environment

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.
