01 What we build
Boards that hold up in the field.
02 Services
Eight disciplines. One point of accountability.
01
PCB Design
Schematic capture, multilayer layout, SI/PI simulation and fabrication-ready output.
02PCB Fabrication
Quick-turn prototypes and bulk runs — single-sided, multilayer PTH and metal-core.
03PCB Assembly
Full, partial and consigned turnkey SMT/THT with free DFM, 100% AOI and BGA X-ray.
04Component Sourcing
BOM scrubbing, multi-distributor pricing, obsolete parts and scheduled call-off stock.
05Turnkey Development
One quote for fabrication, components, assembly and enclosure. Prototypes in 24 hours.
06Reverse Engineering
Rebuild a board with no data — CAD recovered, then redesigned around current parts.
07Inductor Design
Ferrite coils, SMPS transformers, HV coils and EMI filter chokes.
08Enclosure Design
Mechanical design and on-demand FDM printing in PLA, ABS and PETG.

04 Engineering process
Six gates between idea and dock.
-
Gate 01
Specification & feasibility
Your requirement becomes a written engineering specification, with component and compliance risks named up front.
Written spec & risk register
-
Gate 02
Schematic & BOM
Capture, part selection against real availability, and a validated BOM you can cost before a track is drawn.
Costed, lifecycle-checked BOM
-
Gate 03
Layout, SI & PI
Impedance-controlled routing with DC-drop and signal-integrity simulation, then DFM and DFT review before release.
DFM report & CAD project
-
Gate 04
Prototype & validation
Fabricated, populated and tested in-house — as fast as 24 hours. Photos of the first unit before volume starts.
First-article photos for sign-off
-
Gate 05
Production release
Panelised data, stencil, process parameters and fixtures locked. Sourcing moves to scheduled call-off.
Frozen production data pack
-
Gate 06
Build, test & despatch
100% AOI and net-list test, functional test where specified, then despatch on our transport or via Blue Dart.
Test records & despatch note
05 Manufacturing
One building. No hand-offs.
Fabrication, assembly and test on one site in Bhavnagar — which is why a change on Tuesday is a tested board on Thursday.

06 Industries served
Eleven sectors, one standard of rigour.
Each sector is governed by one constraint that decides the design. We build to that constraint — not to a house template.
- 01 MiningVibration, dust ingress and thermal cycling
- 02 Energy meteringAccuracy held across temperature and load
- 03 CommunicationThe stack-up decides whether it passes EMC
- 04 Power supplySwitching loops and magnetics as one
- 05 Food processingSurvives steam, caustic wash and condensation
- 06 Consumer electronicsEvery saving repeats on every unit built
- 07 HealthcareLow noise, running continuously around people
- 08 Agricultural equipmentOutdoors, hosed down, on an unstable supply
- 09 AerospaceThe build record matters as much as the build
- 10 PharmaceuticalThe audit trail is the deliverable
- 11 Electrical apparatusHigh current, high voltage, tight creepage
- → Your sectorTell us the constraint that governs it
07 Why choose us
What customers actually buy.
Rarely just a board. Usually a schedule they can commit to — and an engineer who picks up the phone.

Same price — declare your requirement with the order.
NDA
Before files move
Signed on request, and your designs never go to third parties.
10 Client feedback
In their words, not ours.
One of the best electronics and automation-based solution providers in Bhavnagar. Timely delivered a lot of 5k PCBs of my product.
I have seen every solution by Hallmark PCB Services — fully satisfied. Really great work.
Awesome PCB printing quality. Received in two days.
Gerber files, centroid data and a bill of materials. If the PCB order is already with us and your Gerbers include silkscreen, copper and solder-paste layers, we only need the centroid and BOM.
No. One prototype or a million pieces. We also charge no setup cost on assembly — quoting is quantity-based.
Two to five weeks for a full turnkey order, covering PCB manufacture, procurement and assembly. Rapid prototypes in as little as 24 hours.
Yes — down to 0.25 mm pitch, with X-ray inspection on every BGA. Please tent any vias under the BGA with solder mask.
Gerber RS-274X with Excellon drill data. We also accept ODB++, Protel .PCB / .PCBDOC and Eagle .BRD. We cannot accept 274D.
