PCB Manufacturing Introduction:

Experience cutting-edge PCB fabrication with insulation materials including FR4, aluminum, copper, ceramic, PI, and PET. Our factory excels in 1 to 12-layer boards with finished plate thickness starting from 0.07mm (+5%/-6% tolerance). Inner layer copper thickness ranges from 18-70μm, and outer layer copper thickness from 20-140μm.

Choose from a range of solder-resist colors and lettering options. Our surface treatments include anti-oxidation, HASL, immersion gold, and more. Explore specialized processes like thick copper plating, impedance control, and single-layer copper foil gold finger plates. Reinforce with materials like FR4, steel, and electromagnetic shielding film.

Discover the potential in a compact size of 50mm x 100mm, ensuring precision with 0.065mm/3mil outer/inner line width and spacing. We adhere to minimum solder resist ring width, solder bridge width, solder mask window, and aperture requirements. Our products maintain impedance tolerance at 10% and shape tolerances of +0.05mm G laser +0.005mm.

Forming methods include V-cut, CNC, and punching to meet your fabrication needs. Join us in shaping the future of electronics with our precise, versatile, and dynamic PCB offerings.

PCB Manufacturing Parameters:

PCB Manufacturing Process:

1. Gold-plating process: the vertical HASL process is very difficult to flatten very thin pads, which brings difficulty to SMT placement. In addition, the shelf life of the HASL is very short, and gold-plating just solves the problem. these problems.

2. Immersion gold process: The purpose of the immersion gold process is to deposit a nickel-gold coating with stable color, good brightness, flat coating and good solderability on the surface of the printed circuit board. Basically, it can be divided into four stages: pre-treatment (oil extraction, micro-etching, activation, post-immersion), nickel immersion, gold immersion, and post-treatment (waste gold washing, DI washing, drying)

3. Leaded HASL: Leaded eutectic temperature is lower than lead-free, the specific amount depends on the composition of the lead-free alloy, such as the total gold of SNAGCU 217 degrees, the soldering temperature is the eutectic immersion plus 30 degrees or 50 degrees, It depends on the actual adjustment, the lead eutectic is 183 degrees, the mechanical strength, brightness, etc. are better than lead-free.

4. Lead-free HASL: lead will increase the activity of tin wire in the soldering process, lead-tin wire is better than lead-free tin wire, but lead is poisonous, long-term use is not good for human health, and lead-free tin will It is brighter than lead-tin melting, so the solder joint is much stronger.

5. SOP (anti-oxidation): It has anti-oxidation, thermal shock resistance, and corrosion resistance. It is used to protect the copper surface from rusting (oxidation or carbonization) in a normal environment: but in the subsequent welding high temperature, this protection The film must be easily removed quickly by the flux so that the exposed clean copper surface can be melted and soldered immediately in a short time to become a firm solder joint.
