Below is an EV battery cell contact system manufactured by PCBONLINE (www.pcbonline.com). We can design and manufacture the CCS according to different EV or HEV requirements. Here are some knowledge to share:

1. In a lithium battery pack for EVs and HEVs, a cell contact system connects the battery cells through parallel and series circuits, and the thermistors in the CCS reflect the cell temperature changes to the BMS (battery management system) so that the BMS can control the status of the battery pack.

2. According to different PCBs or cables in the cell contact system, there are flexible PCB CCS, FR4 PCB CCS, the earliest wiring cable CCS, flexible flat cable CCS, and flexible die-cutting circuit CCS. Nowadays, flexible PCB CCS has the most mature process and the highest success rate.

3. A flexible PCB cell contact system comprises a flexible PCBA, busbars, and insulation films.

Most high-frequency PCBs are PTFE-based PCBs or Teflon PCBs. Some can be PTFE/FR4, PTFE/ceramic, PTFE/copper/FR4, etc, hybrid-substrate-lamination boards. Do you need high-frequency PCB boards or assemblies for applications of RF, telecommunications, automotive, military, etc? You can contact PCBONLINE at [email protected]!

Flexible PCBs are used in various car systems and modules. Especially, electric vehicles (EVs) use more flexible PCB or FPCs. Among the many flexible PCB assemblies (PCBAs), the flexible PCB sensors and lithium-ion battery cell contact systems have the most values.

provides one-stop FPC manufacturing and assembly, and can further assemble the PCBA into these automotive modules and systems. The image shows examples of cell contact systems we made.

HDI PCB or high-density-interconnect printed circuit board has extremely small trace width and space and blind/buried micro vias. Rigid-flex PCB has polyimide inner layers and FR4 outer layers that are laser cut to expose the flex circuit boards. Both are advanced circuit boards that have high difficulty in design and manufacturing.

How about manufacturing HDI rigid-flex PCB like this one by ? PCBONLINE has expertise in all types of PCBs since 1999. You can visit us at www.pcbonline.com.

We are excited to call the last working day of 2023 and embrace the incoming new year!

If you need PCBA box build assembly in 2024, the EMS manufacturer PCBONLINE can meet your demands.

Yeah, it is the flying probe test in the PCB fabrication process. It uses 4 needles to inspect the circuit continuity of the PCB. This is a basic PCB test.

For high-end PCBs used in medical, defense, automotive, and aerospace applications, the PCB manufacturer has the four-terminal sensing (Kelvin test) to ensure the micro resistance within the tolerance range.

We just published an original and comprehensive guide to the PCB fabrication process for all PCBs. Its URL is https://www.pcbonline.com/blog/pcb-fabrication-process.html.

High-frequency PCB manufacturing is highly demanding. For example, there must be no drill dirt or contamination in the PTH walls.

Before playing copper, the PCB manufacturer PCBONLINE uses the Plasma method to eliminate all possible contamination before plating copper.

PCBONLINE has been a one-stop PCB and PCBA manufacturer since 1999. We provide high-frequency PCB manufacturing and assembly. All high-frequency laminate models are available and we have their stocks to satisfy the production demands quickly.

You can go to our high-frequency PCB webpage https://www.pcbonline.com/PCB-FAB/High-Frequency-PCBs/ to explore details. Contact [email protected] for a quote.

High-frequency means ≥ 300MHz (wavelength ≤ 1m), and microwave is ≥ 1GHz (wavelength ≤ 300mm).

The printed circuits made using high-frequency and microwave laminates are high-frequency PCB and microwave PCB.

If the PCB materials are high-frequency laminates + FR4 laminates, the high-frequency PCB is a hybrid multilayer board.

If the PCB materials are high-frequency laminates + metal laminates, the high-frequency PCB is a high-frequency MCPCB.

Below is high-frequency MCPCB manufactured by .

PCBONLINE is a one-stop high-frequency PCB manufacturer with strong capabilities providing fast delivery. If you want to check the high-frequency PCB capabilities at PCBONLINE, check its high-frequency PCB webpage at https://www.pcbonline.com/PCB-FAB/High-Frequency-PCBs/.

After LED PCB fabrication and assembly, the electronic manufacturing service provider PCBONLINE provides an LED light source test to see whether the wavelength and color temperatures satisfy the demands of the application.

Particularly, for LED plant growth lights, a light source test is critical. At PCBONLINE, we can customize LED light power, lumen, color temperatures (RGB and RGBW), and wavelength.

If you need LED PCB design, PCB manufacturing, custom-made LED beads, PCB assembly, and finished assembly, you can choose PCBONLINE, and check our LED capabilities from our LED PCB webpage at https://www.pcbonline.com/PCB-FAB/LED-PCB/.

These are two aluminum nitride PCB prototypes manufactured by PCBONLINE. The ceramic circuit boards are manufactured completely, clean, bright, and without any oxidation. Its back side is specially treated.

We can make ceramic PCBs with single and double components-mounting sides, and the ceramic substrate can be AlN, alumina, SiC, and Si3N4. Explore ceramic PCBs from https://www.pcbonline.com/PCB-FAB/Aluminum-Nitride/.

PCB layout is the first step to have printed circuit boards manufactured and assembled. You need to place components and route wires. Trace width and space, impedance, electromagnetic compatibility, and thermal dissipation are all factors to consider in PCB layout.
The one-stop advanced PCB manufacturer PCBONLINE has its R&D team and can design PCBs as well as product enclosures for you.

This is the flexible PCB (FPC) LED strip assembly process. The LED strip is infinitely long.

At PCBONLINE, we can assemble LED chips and seal them with waterproof glue on infinitely long FPC.

We 100% test the functionality and appearance before shipping to ensure that every LED strip is in good condition after customers receive it.

Infinite-length flexible PCBs are not only used for LED light strips.

They are increasingly favored by engineers because they are low-cost and can be cut like cables.

We noticed that more and more ultra-long sensing modules and long-distance signal transmission fields also use this technology.

If you design flexible PCBs, you may have heard about electromagnetic films. An electromagnetic film is laminated on a flexible circuit board when signal lines route on the outmost PCB layers. It shields EMI (electromagnetic interface).
