What are the applications of multi-station dispensing & soldering inspection machines in automotive
source：www.cnkaihui.com | Release time：2026年09月22日1、 Vehicle mounted controller (ECU/VCU/MCU/BCM body control module)
1. Selective soldering of PCBA board: precision spot welding/drag welding of connector pins, power device pins, and plug-in terminals; Automatically detect defects such as virtual soldering, solder leakage, insufficient soldering, excessive soldering, continuous soldering, solder beads, and solder offset.
2. Component reinforcement glue: Apply stress reinforcement glue to the root points of large capacitors, connectors, inductors, and BGA/QFN chip pins to reduce the risk of solder joint cracking caused by vehicle vibration and thermal cycling; Detect the width, height, breakage, overflow, shortage, and bubbles of the adhesive strip.
3. Shell sealing adhesive: The ECU shell is sealed with silicone gel to complete the 3D shape detection of the adhesive path, ensuring the waterproof and dustproof IP protection level, and preventing water leakage from causing electronic control failure of the entire vehicle; Support MES barcode binding to achieve full process traceability of individual items.
2、 Vehicle mounted sensor module (pressure, temperature, millimeter wave radar, laser radar, oxygen sensor, camera module)
1. PCB soldering for radar/camera module: precision soldering of FPC flexible board, connectors, and photosensitive chips; For non-contact welding of optical components, avoid high temperature damage to photosensitive elements.
2. Optical cavity sealing glue: sealing glue for laser radar, car camera housing, lens bonding glue; 3D visual inspection of the cross-section of the adhesive road, controlling the width, height, breakage, and bubbles of the adhesive to ensure airtightness and resist the effects of high and low temperatures, as well as water vapor.
3. Bottom filling of sensor chip: BGA chip bottom filling adhesive dispensing and adhesive quantity detection, improving vibration and impact resistance performance, meeting long-term reliability of vehicle specifications.
3、 New energy three electric electronic components (BMS battery management module, OBC car charger, DC-DC power board)
1. Selective soldering of power board components: soldering of power MOS, IGBT, relay, and high-voltage connector terminals; Detect the wetting status and tin content of solder joints to eliminate the risk of virtual soldering heating and fire.
2. Thermal conductive adhesive and sealant dispensing: Thermal conductive silicone adhesive is used for power devices, and sealant is used for the shell; Detect overflow, shortage, and adhesive layer thickness, while balancing heat dissipation and insulation sealing.
3. Conform Coating: Spray/glue the local three proof paint to detect any omissions, thin coatings, or bubbles in the coating, in order to prevent moisture and salt spray corrosion of high-voltage circuit boards.
4、 Vehicle display and human-computer interaction components (dashboard, central control screen, HUD head up display, vehicle touch module)
1. Solder the FPC and backlight board connectors of the display screen, and perform precise spot welding on the soft board to avoid pulling and breaking the solder.
2. Screen border glue and backlight module adhesive glue; Check the continuity and overflow of the glue path to prevent glue from contaminating the optical area.
3. Repair welding and appearance inspection of PCB solder joints for buttons and knobs.
5、 Car harness connectors, high-voltage connectors, relay modules
1. Welding operation between wire harness terminals and PCB board, replacing manual welding; Detect pad infiltration, cold welding, and wire offset.
2. Apply sealant and fixing adhesive to the connector housing, check the adhesive path, and ensure that the joint is waterproof.
6、 Vehicle mounted actuators and lighting electronics (lamp drive module, motor drive, EPB electronic handbrake module)
1. Solder the components of the LED car light driver board, and inspect the adhesive path before sealing/gluing the light board.
2. Strengthen the welding points of the motor drive power board and apply adhesive to reinforce the pins to resist high temperatures and continuous vibrations in the engine compartment.
