The voltage regulator module is an indispensable component in the on-board computer. Its main function is to stabilize the power supply voltage and ensure that the on-board computer can work normally in various environments.

In vehicle-mounted computers, fluctuations and instability in the power supply voltage may affect the operation of the computer or even cause the computer to malfunction.

Therefore, the role of the voltage regulator module is crucial. It can stabilize the power supply voltage within a certain range, ensure the normal operation of the on-board computer, and improve its stability and reliability.

At the same time, the voltage regulator module also has functions such as over-current protection and over-voltage protection, which can cut off the power supply in time when the power supply is abnormal and protect the on-board computer from damage. Therefore, the voltage regulator module is an indispensable and important component in the on-board computer.

Which voltage regulator module packaging method is more suitable for vehicle-mounted computers?

In on-board computers, surface mount package (SMT) voltage regulator modules are more suitable. The following is a detailed analysis and explanation:

Environmental requirements for on-board computers

Vehicle-mounted computers usually need to work in harsh environments, such as high temperature, low temperature, vibration, etc. Therefore, there are high requirements for the packaging method of electronic components.

Comparison of through-hole and surface mount packages

Direct plug-in package

Advantages: The initial cost of plug-in packaging is relatively low due to its simple design and installation method.

Disadvantages: Due to its large size, it may not be suitable in compact vehicle environments. In addition, because it is directly exposed to the external environment, it is easily affected by vibration, dust, etc., resulting in unstable performance.

Surface mount package

Advantages: Surface mount packages are small and lightweight, saving valuable circuit board space. In addition, due to its tight packaging, it can effectively resist the influence of external environment, such as vibration, dust, etc.

Disadvantages: Surface mount packages are more expensive to manufacture than through-hole packages.

Advantages of surface mount packaging in automotive computers

1. Save space: In on-board computers, space is usually very limited. The use of surface mount packaged voltage regulator modules can effectively save circuit board space, leaving more space for layout of other electronic components.
2. Improve reliability: Since the surface mount package can effectively resist the influence of the external environment, the reliability of the voltage regulator module can be significantly improved. This is critical for in-vehicle computers operating in harsh environments.
3. Easy to integrate and repair: Surface mount packaging allows multiple voltage regulator modules and other electronic components to be easily integrated into one module, thus simplifying the circuit board layout and repair process.

Which brand of voltage regulator module is better to choose for on-board computers?

When choosing a voltage regulator module for an on-board computer, you need to consider multiple factors, including brand, performance, reliability, stability, etc. The following are some well-known voltage regulator module brands in the market for your reference:

Then touch the pin and pad with a soldering iron tip and solder the pin and pad together. Note that the welding time should not be too long to avoid damaging the components or PCB board.

Check welding quality

Check whether the welding is firm and whether there are any weak welding, missing welding, etc. If poor welding is found, it should be repaired or re-welded in time.

Post-processing

Cut off excess pins and gently wipe the PCB surface with an alcohol cotton ball or soft cloth to remove stains and oxides produced during the soldering process. Carry out functional tests to ensure that all circuits function normally and there are no short circuits or open circuits.

2. Heating the soldering piece: Touch the soldering iron to the soldering point. Firstly, keep the soldering iron heating all parts of the soldering piece, such as the leads and pads on the printed circuit board, so that they are heated. Secondly, pay attention to the flat part (larger part) of the soldering iron tip. ) contact the weldment with a larger heat capacity, and the side or edge part of the soldering iron tip contacts the weldment with a smaller heat capacity to keep the weldment evenly heated.
3. Melt the solder: When the weldment is heated to a temperature that can melt the solder, place the solder wire on the solder joint, and the solder begins to melt and wet the solder joint.
4. Remove the solder: When a certain amount of solder is melted, remove the solder wire.
5. Remove the soldering iron: When the solder completely wets the solder joint, remove the soldering iron. Note that the direction of removing the soldering iron should be approximately 45°.

It has the advantages of easy replacement and suitable for mass production.

Electronic component thermal design planning

Thermal design is one of the key factors to ensure the normal operation of electronic components on the PCB. Electronic components generate heat when working. If the heat cannot be effectively dissipated and controlled, it will cause the electronic components to overheat and damage or affect their performance. Therefore, during the PCB design stage, designers need to consider thermal design issues, including heat dissipation methods, selection of thermal conductive materials, and heat dissipation. Usually, heat dissipation measures such as radiators and fans are used on the PCB to ensure that the operating temperature of electronic components is within a safe range.

Electronic component processing and manufacturing technology

The manufacturing process of PCB boards mainly includes substrate production, circuit production, component installation, welding, testing and other links. During the production process, issues such as material selection, processing accuracy, and surface treatment need to be considered.
