Experience in the field of impedance control

      With more than 10 years of PCB impedance manufacturing experience, the engineering technology department of Huihe Circuits has developed several key processes to ensure that the engineering, material control and manufacturing centers can better control impedance.

Impedance modeling software and impedance testing hardware

Huihe Circuit uses impedance modeling software and impedance testing hardware to meet your impedance control needs. The "SpeedStack" and "CITS" toolsets of Polar Instruments combine high-quality field solutions and a comprehensive material library to ensure that your design can be successful the first time.

Etching equipment configuration

Once the impedance control board has been exposed and developed, it must be placed in an etching machine for etching. The etching machine must accurately set parameters such as speed, temperature, pressure, nozzle direction and angle to minimize side erosion. With years of experience in the printed circuit board industry, Huihe Circuits has a mature etching process to ensure that it meets the strict impedance tolerances required by customers.

Incoming material inspection and supplier management process

In the process of cooperation with major suppliers, Huihe Circuit can ensure that the performance of the raw materials (laminated core board, prepreg, copper foil) received by Huihe Circuit is always consistent.

Laser direct imaging equipment

The LDI equipment avoids the line width change due to the expansion/contraction of the dry film, and at the same time forms a clearer image on the copper surface, making the line etching more accurate.
