As a manufacturer of wireless charging solutions, the car wireless charging wood block is generally fixed with: glue, tie, screws. You can DIY according to your own customary preferences.
Today, mainly about glue, glue has many requirements, the following specific sharing of the three wireless charging module glue related issues.
Car wireless module as PCBA components highly integrated miniaturized electronic parts, each customer has a loose, heat, water, insulation and many other potential problems, glue is an important material to help it solve such problems.
1. Epoxy resin adhesive: general application for single-component temperature curing epoxy resin adhesive, common application color is black and white, transparent. It is a high-strength anti-aging and high-temperature adhesive material. Can strengthen the fastening package chip, components, making it more secure anti-vibration anti-drop; can cover the chip parameters, circuit design and other confidential, acid and alkali-resistant confidential not easy to be disassembled; can seal a single component or the entire product, protect its waterproof, dustproof and insulation, from external interference, improve anti-aging. Can pass SMT high temperature without being damaged, in addition to increasing a certain degree of thermal conductivity. It is recommended to use low temperature curing adhesive, 60 or 70 degrees curing, to protect some wireless charging module from high temperature curing damage, can be quickly cured.
2.UV adhesive: UV irradiation light curing, can do seconds curing rate, to meet the requirements of high-volume rapid production. It can also play a protective seal, bonding reinforced components, common application color transparent, translucent, in most cases not over SMT soldering high temperature.
3.Tri-proof paint / electric anti-glue: can be divided into self-drying or UV curing, common color transparent, cured with fluorescent easy to detect. Ultra-low viscosity, high-speed spraying of large areas throughout or local wireless charging module and other products, thickness requirements in the tens of um level, the cost is relatively low. After curing, it can be waterproof, moisture-proof, salt spray, insulation and high and low temperature resistance. Simple operation without equipment can be brushed, or even soaked. Among them, UV tri-proof paint can reach 100% solid content, 10 seconds curing rate, suitable for high-end high requirements of PCB module products, UV tri-proof adhesive can also do UV light curing and moisture dual curing process.
