Description

LED Light SMT PCB Board Aluminum Electronic Multilayer PCBA


♦ What is multilayer PCBA?


Multilayer PCBA (Multilayer Printed Circuit Board Assembly) is the fully assembled board that contains three or more conductive copper layers laminated together with insulating dielectric material. These internal layers are interconnected by plated-through, blind or buried vias, and carry traces, power planes and ground planes. After the bare multilayer PCB is fabricated, electronic components (both SMD and THT) are soldered onto its outer surfaces, creating the functional multilayer PCBA.

​​

Key points:


1. Structure

    • Alternating layers of copper foil and prepreg/core are pressed into one rigid board.
    • Inner layers are etched beforehand; outer layers receive components and final plating.
    • Vias (through, blind, buried) provide layer-to-layer connectivity without enlarging the board.


2.Assembly flow

    • Identical to standard PCBA: solder-paste printing → pick-and-place → reflow (and/or wave) soldering → AOI/X-ray/ICT → final test.
    • Extra precautions for warpage and via reliability because of the thicker, high-layer-count substrate.


3.Design advantages

    • Dense, high-speed or RF circuits with dedicated power/ground planes for low noise.
    • Miniaturization—more circuitry per cm², essential for smartphones, wearables, aerospace, medical implants, etc.
    • Controlled impedance, better EMI shielding and thermal management compared with single- or double-sided boards.


4.Typical layer counts

    • Consumer products: 4–12 layers.
    • High-end servers, telecom, military: 20–60 layers.
    • Specialty suppliers can exceed 100 layers, but cost and yield become critical.
