Multilayer PCB Manufacturer in India | OM Electronics

What is a Multi-Layer PCB?

Multi-layer PCBs consist of multiple layers of conductive material and insulating layers, which allow for more compact and complex designs. These PCBs are ideal for devices that require high-speed signals, high-density interconnections, and advanced electrical performance.

As a multilayer PCB manufacturer in India, OM Electronics fabricates 4-layer, 6-layer, 8-layer, and up to 16-layer boards with controlled impedance, blind and buried vias, and HDI (High Density Interconnect) capability. Our Mohali production facility works with FR4, high-Tg, and halogen-free laminates certified to IPC-6012 Class 2/3. We serve aerospace, 5G telecommunications, high-speed digital computing, and advanced medical electronics sectors — with Gerber review, DFM analysis, and impedance stackup consultation included at no extra charge. Start with our PCB design services for complex stackup planning and validate with PCB prototyping before full production. For thermal-intensive layouts, also see our aluminum PCBs and metal core PCBs.

Why OM Electronics is the Best Choice for Multi-Layer PCBs?

At Om Electronics, we follow a meticulous process to manufacture multi-layer PCBs that meet the highest standards of quality and reliability. From initial design to final testing, we ensure each step is executed with precision to deliver superior performance. Our expert team uses cutting-edge technology and the best materials to produce durable and high-functioning multi-layer PCBs for diverse industries.

Design

Our engineers collaborate with you to develop optimized PCB designs for your specific needs. We focus on creating efficient, high-performance layouts while considering factors like signal integrity and manufacturability to ensure your design is both functional and cost-effective.

Layer Preparation

Each layer of the multi-layer PCB is carefully prepared using premium copper and laminate materials. We meticulously clean, etch, and treat each layer to ensure it meets the required electrical and mechanical specifications, ensuring a solid foundation for the final product.

Stacking

Using advanced, high-precision equipment, we etch and drill the layers with extreme accuracy. This ensures that the intricate circuit paths and holes are formed with tight tolerances, crucial for maintaining signal integrity and ensuring the PCB functions flawlessly under varying conditions.

Etching & Drilling

Using advanced, high-precision equipment, we etch and drill the layers with extreme accuracy. This step involves removing excess copper from the layers to create the circuit pathways, while precise drilling is performed to make holes for component leads and vias.

Final Testing

Every multi-layer PCB undergoes rigorous electrical testing to ensure it meets the design specifications. We conduct several tests, including continuity testing and impedance testing, to guarantee that each board operates as expected and meets our strict quality standards before delivery.

On-Time Delivery

At Om Electronics, we understand the importance of meeting deadlines. We are committed to delivering your multi-layer PCBs on time, whether for small-scale prototypes or large-scale. We ensure that each order is completed and shipped on schedule, allowing you on track with your project timelines.

Frequently Asked Questions — Multilayer PCB

Key questions answered about multilayer PCB manufacturing at OM Electronics, Mohali, North India.

OM Electronics manufactures multilayer PCBs from 4 layers up to 16 layers at our Mohali, Punjab facility. For specialised high-layer-count boards (18+ layers) used in aerospace, 5G base stations, or server-grade computing, we can discuss custom requirements. Our standard production covers 4-layer, 6-layer, 8-layer, 10-layer, and 12-layer configurations.

Yes. OM Electronics supports controlled impedance manufacturing for multilayer PCBs with tolerance of ±10%. We accommodate single-ended impedances (50Ω, 75Ω) and differential pair impedances (90Ω, 100Ω) as required for high-speed digital, RF, and telecommunications designs. Stackup consultation and Gerber DFM review are included at no extra charge.

We work with standard FR4 (Tg 135°C) for general-purpose multilayer boards, High-Tg FR4 (Tg 150°C and 170°C) for lead-free assembly and high-temperature environments, and Halogen-Free FR4 for applications requiring reduced environmental impact and compliance with IEC 61249-2-21. Hybrid stackups combining different laminates are also available for specialised applications.

Prototype multilayer PCBs (4–8 layer, small quantity) typically ship within 5–7 working days. Production quantities and higher layer counts (10–16 layers) require 10–15 working days. Quick-turn options are available for urgent prototype requirements. We provide pan-India delivery from Mohali, with express shipping available to Chandigarh, Delhi, Bengaluru, and other major cities.
