This rigid flex board is an 8L security board with a blue solder mask, and the surface treatment is immersion gold. Its size is relatively large, and the main difficulty is that the board has multiple sets of bifurcation impedances. Next, we will give an introduction to the board based on the difficult control of the production of impedance boards.

1. Stack up

2. Production process:

Cutting → inner layer → inner layer etching → inner layer AOI → brown oxidation → lamination → drilling → PTH and plating → outer layer → outer layer pattern plating → outer layer etching → outer layer AOI inspection → medium Test → impedance test 1 → Pretreatment of solder mask → Solder mask → impedance test 2 → silkscreen → immersion gold→ Routing→ E-test → FQC → Packing

3. Manufacturing difficulties

As circuit designs become more complex and high-speed, how to ensure the integrity of various signals (especially high-speed signals), that is, to ensure signal quality, has become a problem. At this time, it is necessary to use the transmission line theory to analyze, and the characteristic impedance matching of the control signal line becomes the key. Inadequate impedance control will cause considerable signal reflection and signal distortion, leading to design failure. Common signals, such as PCI bus, PCI-E bus, USB, Ethernet, DDR memory, LVDS signals, etc., require impedance matching. Impedance control ultimately needs to be realized through PCB design, which also puts forward higher requirements on PCB board craftsmanship. For PCB production, we control impedance through 4 links:

a. The thickness of the dielectric layer, namely the choice of PP and the core board, has a great influence on the impedance.
b. Line width/line spacing control, impedance line width/line spacing control directly affects the impedance value, so the impedance line tolerance control is generally more stringent than ordinary lines.
c. The control of copper thickness, and the influence of copper thickness uniformity on impedance is also a link that cannot be ignored. Therefore, when producing impedance boards, we generally reduce the electroplating current, extend the electroplating time, and ensure better uniformity.
d. Solder mask thickness control. The thickness of the solder mask ink also has a certain influence on the solder mask value, but its influence is not as great as the first three, so it is often ignored by people and leads to poor impedance.

4. Application areas:

This circuit board is used in the security electronics-camera security system host. The camera security monitoring system is the application of the physical principles of the security monitoring system. Microwave or optical fiber, coaxial cable, etc., in a closed circuit, the internal loop speed of video signal transmission, real-time images, truly reflect the object being monitored, and security surveillance cameras The system consists of camera images, display and recording system integrity. At the same time, set up the alarm system and equipment to provide legal intrusion alarms, the alarm host that the birthplace model outputs, the host triggers the alarm, and the video surveillance system records.
