A-TECH lead free hasl rohs lead bulk production for wholesale

Company Advantages
1. A-TECH is produced by purchasing advanced machines for production. Its solderable surface is protected from the oxidation
2. With complete quality control system, lead free hasl rohs is well received by global customers. It is widely used in different electronics industries, such as telecommunication and consumer electronics
3. This product provides enough stability. During the production, the thermoplastics have been added to control the central torsion movement of the foot. Its robust structure allows it to be used in harsh environments
4. The product features wearer friendliness. It is designed according to the principle of foot biomechanics which considers how to provide support and adjuvant therapy to the foot. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo
5. It meets durability requirements. It has passed relevant testings which verify its resistance to mechanical damage, resistance to dry and wet heat, resistance to cold liquids, oils and fats, etc. It can reduce the electrical signal loss and provides the highest efficiency

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.
