Multilayer PCB is a PCB that is made up with three or more conductive copper foil layers. There are increasing demand for multilayer PCBs. It is becoming much more popular due to the advantages of drive for electronics to be smaller, faster, and more powerful. The ability to create multilayer boards opens up a world of possibilities allowing the engineer to create more densely populated circuit boards which allows miniaturization.This is a huge benefit that double sided boards are not able to offer.
Multilayer PCB Benefits
• Small Size: One of the most primary benefits of using multilayer PCBs is their size. Due to their layered design, multilayer PCBs are inherently smaller than other PCBs with similar functionality. This presents a major benefit to modern electronics, as the current trend is working toward smaller, more compact yet more powerful gadgets like smartphones, laptops, tablets and wearables.
• Lightweight Construction: With smaller PCBs comes less weight, especially as the multiple connectors required to interlink separate single and double-layered PCBs are eliminated in favor of a multilayered design. This, again, is beneficial for modern electronics, which are geared more toward mobility.
Hongmy circuits offer two types of gold finish: Electroless Nickel Immersion Gold (ENIG) as a surface finish for the whole PCB, and hard plated gold over plated nickel for edge-connector fingers. Electroless gold gives excellent solderability, but the chemical deposition process means that it is too soft and too thin to withstand repeated abrasion. Electroplated gold is thicker and harder making it ideal for edge-connector contacts for PCBs which will be repeatedly plugged in and removed.
For gold finishing, we can provide gold thickness 1U" to 30 U",which can fullfill your needs of good quality PCBs.
For Glass Transition (Tg) Value, we have Tg130, Tg 135, Tg 150, Tg170 for your choice.
We can make PCBs for many products, like communication equipment, instrument, OA equipment, Driver, Control system, etc
Any needs of PCBs, pls feel free to contact us.
