Description

FPC products are primarily used in the fields of medical Health, automotive, communication, backlight, smart homes, etc. In the supply of FPC products, JONVER has a rich product line and advanced production technology. Our FPC products use high-quality substrates and cover films, and are designed and manufactured with precision circuitry processes to ensure outstanding electrical performance, mechanical strength, and durability. At the same time, we can also customize FPC products according to specific customer requirements to meet the unique application scenarios of our clients.

FPC PRODUCTION PROCESS FLOW FPC PRODUCTION PROCESS FLOW

FPC factory JCEC GROUP

Our factory has a 25-year history and became the first private enterprise specializing in producing flexible printed circuits (FPC) in China.We supply products to several well-known companies, such as Apple, Hewlett Packard, Mercedes-Benz, Wanxiang Group, and Shandong New Energy.

The company has two factories located at different sites:

Jiangyin factory: Located in Jiangyin City, Jiangsu Province, covering an area of approximately 35,000 square meters, it houses 20 SMT production lines and 3 wave soldering production lines, with a total of over300 employees. This factory is primarily responsible for the production and assembly lines of FPC as well as PCB assembly and production lines.

Ahhui Fctory: The company's first phase has the production capacity of 300,000 square meters per year for double-layer and multi-layer FPCs. It has successfully passed various system certifications such as ISO9001, ISO14001, IATF 16949, UL, ISO13485, ISO45001, QC080000, and was recognized as a National High-Tech Enterprise in 2020.

  • The thickness of the copper layer is commonly 35um.
  • The standard thickness of a single-sided board is 0.2mm.
  • The standard thickness of a double-sided board is 0.32mm.

Control standards of FPC line resistance

The typical length of an FPC is within 1m. The standard requirement for customer FPC loop resistance is that: internal circuit resistance ≤1Ω.

Control accuracy of FPC loop resistance

Under the condition of continuous current flow of 1A at an ambient temperature of 25 degrees with a temperature rise of less than 15 degrees,assuming a copper thickness of 35um, a wire width of 0.3mm,

if the wire length is 300mm, the resistance value is 0.513Ω;

for a wire length of 500mm, it is 0.833Ω;

for a wire length of 700mm, it is 1.196Ω;

for a wire length of 1000mm, it is 1.71Ω;

for a wire length of 1200mm, it is 2.051Ω.

(Note: The loop resistance directly affects the wire thickness, wire width, and wire length. In actual production, our company can adjust the wire width and copper thickness according to the customer's resistance requirements to meet the customer's loop resistance specifications.)

Control precision of loop resistance:

Under the FPC scheme, when the copper thickness is 35um,

for wire lengths between 500~700mm,the loop resistance tolerance can be controlled to ≤1Ω;

for wire lengths between 700~1200mm, the loop resistance tolerance can be controlled to ≤2Ω.

  • Rapid Curing: UV glue can quickly solidify under ultraviolet light exposure, significantly shortening the production cycle.
  • High-Strength Adhesion: The cured UV glue possesses high adhesive strength, meeting the demands of various high-strength bonding requirements.
  • Good Transparency: UV glue maintains good transparency after curing, with virtually no impact on light transmission.
  • Environmentally Friendly and Non-Pollution: UV glue produces almost no volatile organic compounds (VOCs) during the curing process, making it environmentally friendly.
  • Simple Operation: The operation of the UV dispensing machine is relatively simple. It only requires applying the UV glue to the area needing bonding and then exposing it to ultraviolet light. This method not only improves production efficiency but also reduces operational difficulty.

HOW TO ORDER FPC

01

To proceed with the FPC design process, youneed to provide detailed 2D and 3D drawings that clearly illustrate the structure of your FPC, including critical components such as conductive paths, insulation layers, and copper foil. These design diagrams will allow us to understand the layout, dimensions, layering, and any special design requirements of the FPC.

02

Please provide your Gerber file.

(If you need help with designing the Gerber, please let us know and we will assist you.)

Please note that for NTC thermistors, fuses, and connectors, it is important to consider adding reinforcement at the bottom.

If you are using a single-layer board, we generally adopt the following layout:
