Smartphones/tablets: Components such as chips, capacitors, resistors, etc. on the circuit board need to be fixed by soldering, and adhesive (such as conductive glue, sealant) needs to be applied at the interface to enhance connection stability; Some core components (such as baseband chips) need to be sealed with waterproof or thermal conductive adhesive to enhance their resistance to drops and high temperatures.
Computers and peripheral devices: soldering of components such as motherboards, graphics cards, and memory modules (surface mount soldering, plug-in soldering), and adhesive anti oxidation at interfaces; The circuit board of the power adapter is encapsulated with epoxy resin to achieve insulation and moisture resistance.
Smart home devices: Control circuit boards for smart speakers, floor cleaning robots, and smart door locks, ensuring stability in humid or dusty environments through glue (fixing wires, sensors), soldering (soldering chips and interfaces), and sealing (moisture-proof and dustproof).
2、 Automotive electronics field
In car electronic components: Circuit boards for in car navigation, dashboard, and infotainment systems, which require soldering to fix automotive grade chips and connectors. Key parts are glued (such as thermal conductive adhesive) to dissipate heat, and some outdoor installed modules (such as reversing radar motherboards) are sealed with waterproof adhesive to adapt to the vibration and temperature difference environment during vehicle operation.
New energy vehicle components: Battery Management System (BMS) circuit board, motor controller circuit board, soldering high-voltage components, dispensing insulation glue to prevent short circuits, sealing thermal conductive sealing glue to improve heat dissipation efficiency, ensuring the safe operation of batteries and motors.
Automotive sensors: Circuit boards for millimeter wave radar and camera modules, ensuring signal stability in high temperature, rain and snow environments through precision dispensing (positioning components), soldering (soldering signal interfaces), and sealing with sealant.
3、 Industrial electronics and automation field
Industrial control board: circuit board for PLC (Programmable Logic Controller), frequency converter, servo drive, soldering high-power components and wiring terminals, adhesive fixed capacitors and other shock prone components, sealed with silicone or resin to achieve dust and corrosion prevention (suitable for dust and oil pollution environments in factory workshops).
Sensors and Instruments: Circuit boards for temperature sensors, pressure transmitters, flow meters, soldering sensitive components, adhesive sealing of wire interfaces, sealing with protective glue to avoid the influence of external environment (such as humidity and electromagnetic interference) on measurement accuracy.
4、 Medical electronics field
Medical equipment circuit boards: Control circuit boards for monitors, ultrasound equipment, infusion pumps, soldering high-precision chips and probe interfaces, dispensing with medical grade sealant (non-toxic, disinfectant resistant), and partially implantable medical equipment circuit boards (such as pacemaker accessories) with biocompatible sealant to ensure safety and stability.
Portable medical devices: circuit boards for blood glucose meters and blood pressure monitors, improved production efficiency through automated dispensing (fixing display screens and button contacts) and soldering (soldering micro components), and sealed with moisture-proof adhesive to adapt to humid environments in home use.
5、 In the field of communication and network equipment
Communication base station components: RF module and optical module circuit board of 5G base station, soldering high-frequency connectors, dispensing thermal conductive adhesive to assist heat dissipation, and sealing waterproof adhesive to adapt to the wind, rain, and ultraviolet environment of outdoor base stations.
Network equipment: Circuit boards for routers and switches, soldered network ports and chips, fixed heat sinks with glue, and some outdoor equipment (such as fiber optic transceivers) sealed with insulating glue to ensure long-term stable operation.
6、 In the field of new energy and power electronics
Photovoltaic inverter: The power devices (IGBTs) on the circuit board need to be soldered, and thermal conductive adhesive is applied to enhance heat dissipation. The whole is encapsulated with epoxy resin to adapt to outdoor high temperature, high humidity, and dust environments.
Energy storage equipment: circuit board for energy storage battery management system, soldering high-voltage terminals, dispensing insulation glue to prevent short circuits, and sealing glue to enhance seismic resistance (suitable for transportation vibrations of mobile energy storage equipment).
7、 Military and aerospace industries
Military electronic equipment: radar systems, communication radio circuit boards, soldering must meet high reliability (anti vibration, anti impact), and special adhesives that can withstand extreme temperatures (-50 ℃~150 ℃) should be used for dispensing and sealing to ensure stability in harsh environments (such as battlefields and high altitudes).
Aerospace electronics: Control circuit boards for satellites and drones require zero defects in soldering processes (to avoid high-altitude failures), and are sealed with aerospace grade sealing glue (such as silicone rubber) to achieve insulation and radiation protection in vacuum environments.
