Electric vehicle circuit board processing

What is an electric car circuit board?

The electric vehicle circuit board is the core control device used to control the start, run, advance and retreat, speed, stop and other electronic devices of the electric vehicle. It is like the brain of the electric vehicle and an important part of the electric vehicle.

The main parameters and functional characteristics of Tianjin electric vehicle circuit board are as follows:

1. Rated voltage: applicable to 12V, 18V, 24V, 36V, 48V, 60V, 72V, 80V;

2. Undervoltage value: the rated voltage of the battery*0.875 (±1V);

3. Current-limiting current: the current-limiting value is 4A~100A (±0.5A)

4. Static power consumption: <2W

5. Speed limit function: XS interface. When the speed is limited, the driving speed is controlled within 20km/h.

6. Over-speed function: magnetic field weakening can be used to achieve over-speed driving, and the maximum speed can reach 1.5 times the rated speed of the motor

7. Cruise mode: XH interface. With 8 seconds automatic cruise and manual cruise two modes

8. 1:1 power assist function: 1:1 interface. The controller gives a corresponding proportion of motor power according to the pedaling force (speed) of the rider.

Electric vehicle circuit board processing manufacturers

Electric vehicle circuit board processing needs to provide information

1. Complete PCB making documents (Gerber files, placement diagrams, steel mesh files) and board making requirements;

2. Complete BOM (including model, brand, package, description, etc.);

3. PCBA assembly drawing.

PS: To report the PCBA function test fee, the PCBA function test method shall be provided.

Electric vehicle circuit board processing flow

1. The customer places an order

Customers place orders according to their actual needs PCB circuit board processing plants, and put forward specific requirements. The processing plant will evaluate its own capabilities to see if it can complete the order. If the manufacturer determines that it can complete the order within the expected time, then the two parties will negotiate to determine the production details.

2. Customers provide production materials

After the customer decides to place an order, he provides a series of documents and lists to the circuit board processing plant, such as the PCB electronic files, coordinate files, and BOM lists needed for production, which are all required.

3. Purchasing raw materials

The circuit board processing plant purchases relevant raw materials from the designated supplier according to the documents provided by the customer.

4. Incoming inspection

Before the circuit board processing, all raw materials to be used are subjected to strict quality inspection to ensure that they are qualified and put into production.

5.PCBA production

When processing circuit boards, in order to ensure production quality, whether it is SMD or solder production, manufacturers need to strictly control the furnace temperature.

6.PCBA test

The circuit board processing plant conducts strict product testing, and the PCB boards that pass the test are delivered to the customer.

7. After-sales packaging

After the circuit board processing is completed, the product is packaged and then delivered to the customer to complete the entire circuit board processing work.

Electric vehicle circuit board processing manufacturers

How much is the processing price of electric car circuit boards?

Tianjin electric car circuit board processing cost = PCB board cost + PCB testing fee + PCB engineering fee (for small batches) + component procurement cost (partially up by 5%) + SMT/DIP welding fee + PCBA testing fee + assembly engineering fee ( Applicable for small batches) + special packaging and logistics costs (if customer needs).

How long does it take to process circuit boards for electric vehicles?

The time structure of Tianjin electric vehicle circuit board processing: component procurement and PCB production + SMT chip processing + DIP plug-in processing + PCBA testing + finished product assembly.

Electric vehicle circuit board processing time details: The purchase of components and PCB is generally placed at the same time. PCB production takes 3-10 days, and the purchase of components is 2-15. The arrival time of components is relatively uncertain. SMT and DIP are added. It takes 3-5 days to get up, PCBA test generally takes 1-3 days, and finished product assembly 2-5 days.
