Frequently Asked Questions
Choosing a PCB manufacturer means weighing certifications, in-house capability, and real sector experience, not just price. Here are the answers engineers and buyers ask for most.
FAQs
About PCB Manufacturing
What is PCB manufacturing, and how is a printed circuit board manufactured?
PCB manufacturing is the process of fabricating a printed circuit board: etching copper layers, drilling and plating holes, and applying solder mask and finish before testing. It’s the fabrication stage, separate from assembly, where components get mounted afterwards.
What makes PC Process different from other PCB manufacturers?
PC Process holds LCSO certification (JSS 52302), India’s defence quality standard. In-house fabrication has earned it HAL, BEL, and ISRO trust for heavy copper, impedance-controlled boards.
What industries do you manufacture PCBs for?
Defence, space and aerospace, telecom, medical electronics, and industrial automation. Each sector carries its own reliability and traceability demands, which is exactly what LCSO and ISO certification exist to verify.
What type of PCB is commonly specified for medical electronics?
Multilayer boards with blind and buried via technology, since medical devices need compact layouts alongside high reliability. PC Process builds these to ISO 9001:2015 standards, the same certification underpinning every board across its industry base.
How do I choose the right PCB manufacturer?
Check in-house fabrication, industry-matched certifications (LCSO for defence, not just ISO 9001), and sector-specific track record, like blind/buried-via expertise for medical devices.
Why choose in-house PCB manufacturing?
If a spec needs adjusting mid-run, say a customer requests a finish change after seeing a first-article sample, there’s one team to talk to, not a subcontractor chain to chase down for a revised timeline.
How do you ensure consistent PCB quality?
PC Process’s quality team reviews every board, whether it’s a single prototype or a full production batch, through DFM review, in-process inspection, automated optical inspection, and 100% electrical testing before it ships, following IPC-standard practice throughout.
What certifications do you hold?
ISO 9001:2015 and LCSO approval under JSS 52302, the certification required for defence-sector PCB supply in India.
Why does LCSO certification matter for a PCB manufacturer?
It verifies traceability and process control at a stricter level than ISO 9001 alone. Defence and aerospace programs require it specifically when qualifying a supplier, which is the certification behind PC Process’s HAL and BEL relationships.
Why does LCSOWhy choose a PCB manufacturer in Bangalore?
A dense electronics and engineering supply base makes sourcing materials and skilled technical labour faster here than in most regions, and it cuts logistics time for customers across South India.
Why is Peenya a hub for PCB manufacturing?
Peenya is one of Asia’s largest industrial estates, developed since the 1970s specifically to concentrate engineering and electronics manufacturing in one connected zone. That density of suppliers is a natural fit for a defence-certified PCB manufacturer.
Do you serve customers across India?
Yes, including defence and aerospace programs, telecom companies, and industrial manufacturers outside Karnataka. Shipping nationwide is standard, with timelines depending on order size and destination.
Does faster turnaround mean lower quality?
No. Quick-turn orders go through the same DFM review, in-process inspection, and 100% electrical testing as standard production runs. Speed changes scheduling priority, not the quality process itself.
What information should I provide for a PCB manufacturing quote?
Gerber files, layer count, board dimensions, material, copper weight, surface finish, and quantity, plus your delivery timeline since quick-turn orders are priced differently from standard runs.
Can you manufacture PCBs from my Gerber files?
Yes, Gerber files (RS-274X) are the standard input for fabrication.
What if my design needs more than just Gerbers?
Drill files and a stack-up drawing may also be requested for complex, multilayer designs, particularly anything with blind or buried vias or tight impedance targets.
Do you provide DFM support before manufacturing?
Design files get reviewed against manufacturing constraints before fabrication begins, and issues are flagged back with suggested corrections, catching problems before a batch has already run rather than after.
Can you handle urgent PCB orders?
Quick-turn manufacturing is available for time-sensitive prototype and low-volume orders. Turnaround still depends on layer count and complexity, so flag urgency at the quotation stage rather than after.
Do you manufacture prototype and production PCBs?
Same in-house process for both. A design can scale from a single prototype to full production without switching manufacturers partway through.
Can you manufacture custom PCB designs?
Layer count, material, copper weight, and impedance get specified per project rather than built to a fixed template, whether that’s a one-off prototype or a repeat production spec.
What PCB materials do you support?
FR4 covers most general electronics. Rogers’ material is for RF and high-frequency applications where signal performance at speed matters more than cost, since FR4’s standard electrical characteristics fall short of RF-grade requirements at those frequencies.
What surface finishes are available?
ENIG, HASL, lead-free HASL, OSP, and immersion silver, with the right pick depending on application, shelf life, and whether the board needs fine-pitch assembly.
What PCB thicknesses can you manufacture?
It depends on layer count and application. A heavy copper or high-layer-count board sits at a different profile than a standard prototype, so confirm your target thickness against your design’s needs at the quote stage.
Is there a minimum order quantity for PCB manufacturing?
MOQs vary by board complexity, layer count, and material.
Can you support repeat production orders?
Once a design and quality baseline are set through a first run, repeat orders follow the same specs without restarting the qualification cycle.
What is the typical PCB manufacturing lead time?
Layer count, complexity, material availability, and testing requirements all factor in, with prototype and low-volume orders generally moving faster than full production batches.
What is the difference between PCB fabrication and PCB assembly?
Fabrication is manufacturing the bare board itself: copper layers, drilled holes, and solder mask. Assembly is mounting and soldering components onto that board afterwards. PC Process’s engineering team handles fabrication in-house; assembly is a separate step outside that scope.
What are multilayer PCBs used for?
Denser, more compact layouts than single or double-layer boards can support. PC Process manufactures multilayer PCBs up to 24 layers.
When should you use heavy copper PCB manufacturing?
Whenever a board needs to carry higher electrical current without excessive heat build-up, commonly power supplies, industrial equipment, and EV charging systems.
Why is controlled impedance PCB manufacturing important for high-speed electronics?
It keeps trace impedance within a tight, specified range, critical for RF systems, telecom equipment, and high-speed digital circuits. Getting it wrong causes signal loss or reflection that’s hard to diagnose after the board is built.
