Do you know aluminum PCB board?
The construction of Hybrid aluminum PCB
In fact, there were few MCPCB guys know the construction of hybrid aluminium PCB.
Even some of them know this type PCB.
In a ‘Hybrid’ aluminum PCB construction a “Sub-assembly” of a non-thermal material is processed independently and then bonded to the aluminum base with thermal materials.
Typical Hybrid aluminum PCB introduces
Due to hybrid aluminium PCB were not used widely, just use by some high tech companies.
So there were necessary introduce the typical Hybrid aluminum PCB.
The most common construction is a 2-Layer or 4-Layer Sub-assembly made from conventional FR-4.
The benefit of Hybrid aluminum PCB
When designed with an adequate number of thermal was this construction is less costly than one composed of all thermally conductive materials, but still provides superior thermal performance over a standard FR-4 product.
We offer one-stop service of PCB Fabrication, layout/design, copy (Gerber, BOM), component sourcing, assembly (SMT ), advanced testing, high standard packing, on time delivery and after-sales service.
FAQ:
Q1. What specifications do you need for PCB quotation?
A: We need your PCB Gerber file,board thickness,copper thickness,surface finishing and quantity to quote you.
Q2. Are you trading company or manufacturer ?
A: We are PCB manufacturer with 12 years experience in this area.
Q3: How about your supply capacity?
A: Our supply capacity is around 2000sqm each day. where our 25 000 sqm factory space hosts R&D, marketing, logistics and procurement operations.
