Advanced PCB Manufacturing with Diverse Materials and Precision Processes

 

PCB Manufacturing Introduction:
Explore our cutting-edge PCB factory, specializing in 1 to 12-layer boards. Our wide range of insulation materials includes FR4, aluminum, copper, ceramic, PI, and PET. With finished plate thickness starting at 0.07mm and above (tolerance +5%/-6%), our boards offer exceptional quality and performance.

Benefit from inner layer copper thickness options ranging from 18-70μm and outer layer copper thickness from 20-140μm. Choose from an array of solder-resist colors and letters including red, green, yellow, blue, white, black, and silver, and experience surface treatments such as anti-oxidation, HASL, immersion gold, and more.

Our PCBs undergo special processes like thick copper plating, impedance control, high-frequency capabilities, and single-layer copper foil gold finger plates with unique configurations. Reinforcement options include Pl, FR4, steel sheet, M glue, and electromagnetic shielding film.

With a maximum size of 50mm x 100mm, our boards offer precision with outer/inner line width and spacing of 0.065mm/3mil. We ensure meticulous attention to detail with minimum solder resist ring width, solder bridge width, solder mask window, and aperture requirements.

Our products maintain impedance tolerance at 10%, adhering to shape tolerances of +0.05mm G laser +0.005mm. Choose from forming methods such as V-cut, CNC, and punching to achieve the desired specifications. Experience the future of PCB manufacturing with our advanced solutions.

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.

 

PCB Manufacturing Advantages:

1. From PCB proofing to SMT placement, one-stop solution, reducing R&D costs and accelerating product launch.

2. Quick quotation and quick response.

3. The delivery date is fast, and the on-time delivery rate is over 95%

4. Excellent materials, advanced equipment, and strict quality system 5. Exclusive customer service one-to-one service, seamless connection throughout the process
