DIP/SMT Electronics Automotive PCB Assembly FR4 Printed Circuit Board With Lead Free HASL
Automotive Electronics
Automotive electronics mainly require two- to six-layer boards, HDI boards and flexible boards. The demand for high-end PCBs will further increase in the electrification and intelligence of automobiles.
Why Is FR4 Material Used In PCB Circuit Board Processing Popular?
The FR4 material acts as the base of any PCB board, the material is laminated with a layer of copper foil, which is laminated using heat and adhesives, and the copper foil can be used to laminate the material from one or both sides. For relatively simple applications, FR4 materials with TG values of 130-140C can be selected. For multi-layer or large-thickness circuit boards, products that have relatively high heat resistance requirements should be selected FR4 materials with TG values of 170-180. With the advent of lead-free welding processes, in addition to TG, TD and other indicators need to be considered together. In addition, in lead-free welding process applications, higher TG values do not always mean better performance. In other words, as end-use applications expand, so will the range of FR4 materials available. Why is FR4 material used in PCB circuit board processing popular?
1.FR4 is a low-cost material.
2. It has a high dielectric strength, which contributes to its electrical insulation properties
3. The material has a high strength-to-weight ratio and is light in weight
4. It is moisture-proof and also has a relative temperature
5. The material has good electrical loss performance
6.FR4 does not absorb water, so it is also suitable for a variety of Marine PCB applications.
7. The material is yellow to light green, perfect for any application.
8. All these characteristics make it suitable for a variety of environments
