♦ What Are Multilayer PCB Boards?

Multilayer PCBs​​ are printed circuit boards consisting of ​​three or more conductive copper layers​​, laminated together with insulating (dielectric) material. These layers are interconnected through ​​plated through-holes (PTHs), vias, or buried/blind vias​​, enabling complex circuit designs in a compact form.

♦ ​​Key Features of Multilayer PCBs​:

✅ ​​High Density​​ – More layers allow for more components and routing in a smaller space.

✅ ​​Improved Signal Integrity​​ – Dedicated power & ground planes reduce noise and EMI.

✅ ​​Better Thermal Management​​ – Heat spreads more efficiently across layers.

✅ ​​Reduced Weight & Size​​ – Replaces multiple single-layer boards with one compact unit.

✅ ​​Enhanced Durability​​ – Multiple layers provide structural strength.

♦ Common Layer Configurations​?​

♦ ​​Manufacturing Process​​:

1. ​​Inner Layer Imaging​​ – Etching circuit patterns on inner copper layers.
2. ​​Lamination​​ – Stacking layers with prepreg and pressing under heat.
3. ​​Drilling​​ – Creating holes for vias and component leads.
4. ​​Plating​​ – Electroless/electrolytic copper deposition for conductivity.
5. ​​Outer Layer Patterning​​ – Applying photoresist and etching outer layers.
6. ​​Solder Mask & Surface Finish​​ – Protecting copper with ENIG, HASL, or OSP.
