Company Advantages
1. A-TECH immersion tin pcb finish is manufactured to meet user requirement specification. Its electric components and the housing have gone through heat treating, stamping, laser cutting, and surface treating. It is widely used in different electronics industries, such as telecommunication and consumer electronics
2. People will find the benefits of this product: the quality is superb, the fit is great and colors are as vibrant as the picture. With a solder mask, it enjoys a good electrical insulation property
3. The quality of this product meets the requirements of many international certifications. It is extremely popular in the markets of Europe, North America, and Asia
4. pcb mask is manufactured based on excellent materials and is designed in accordance with a scientific structure concept. It has the characteristics of heat insulation, heat preservation, flame retardant, impact resistance, corrosion resistance, and anti-aging property. Moreover, it is long-lasting in durability and easy in maintenance.
5. pcb mask has good wear resistance, aging resistance, and tear resistance. It is long in service life and is not prone to cracking, scratching, abrasion, and tearing.


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.




Company Features
1. A-TECH CIRCUITS Co., Ltd. is equipped with strong research strength, having an R&D team dedicated to developing all types of new pcb mask.
2. Our whole members make an effort to built a No. 1 Brand of immersion tin pcb . Get quote!
All A-TECH immersion tin pcb are 100% visually inspected. The QC engineers continuously take random samples for detailed computerized dimensional and material compound analysis. The product is widely used in car tuning events and car repair shops
A-TECH pcb mask is made from polymers that are made up of many many molecules strung together to form long chains that behave differently. Its surface can be treated with matte black primer, clear twill weave carbon, or shining finish
A-TECH immersion tin pcb finish has undergone a series of tests such as tensile strength tests, tear tests, H-Drawing tests, compression tests including set up of its stop force. Processed under CNC molding, the product has precise dimensions
The production process of A-TECH pcb mask involves coagulation, a process that curdles or thickens the polyisoprene into a mass. This process is accomplished by adding an acid. It is packaged with multilayer carbons for shock and crush resistance
Some chemicals and other additives are added to customize the A-TECH immersion tin pcb for the intended use, including anhydrous aluminum silicates as reinforcing fillers. The product brings ultimate style and performance to the car
The product features low-temperature resistance. Due to its amorphous molecular structure, the low temperature has little effect on its properties. The carbon fiber material used in it results in slightly increased velocity
