Vishesh provides complete box build assembly in Bangalore from its dedicated 20,000 sq ft Plant 2 facility. Box build goes beyond PCB assembly — it covers mechanical enclosure fitting, cable and harness assembly, sub-assembly integration, functional testing, and final product packaging, delivering a finished unit ready for end use or dispatch. As part of Vishesh's end-to-end electronics manufacturing services, box build sits at the top of the value chain — where all upstream processes converge into a shippable product.
Vishesh is ISO 9001 and IATF 16949 certified by TÜV Rheinland, serving Automotive, Industrial, Power, and Defense customers who need a single manufacturing partner from bare board to finished unit. Both plants are co-located at Vishesh's Gottigere, Bangalore facility — eliminating inter-vendor logistics, maintaining a single quality system, and reducing time to market. Request a quote →
Box build assembly is the process of integrating all sub-components — PCBAs, mechanical enclosures, wiring harnesses, connectors, displays, and fasteners — into a complete, finished product. Where PCB assembly services produce a populated board, box build takes that board and builds it into the end product a customer can ship, install, or retail.
The business case for consolidated box build is straightforward: fewer vendors means fewer handoffs, fewer quality gaps, and a single point of accountability. When PCBA and box build happen under the same roof — under the same quality management system — defects are caught earlier, traceability is unbroken, and lead times shrink. Customers who previously managed separate PCB assembly and mechanical assembly vendors consistently reduce procurement overhead by consolidating at Vishesh.

Eight stages from customer documentation to dispatch — each tracked under Vishesh's ERP system and executed under ISO 9001:2015 and IATF 16949:2016 quality disciplines.
Customer BOM and assembly drawing review. DFM and DFA feedback provided upfront. FMEA conducted for new product introductions to identify process risks before production begins.
All incoming materials — electronic components, mechanical parts, cables, enclosures — inspected against BOM and customer specifications before entering the production floor.
SMT and THT assembly on Vishesh's three Siemens lines. AOI post-reflow on every board. Functional testing and programming per customer specification. Completed PCBAs transferred to Plant 2 for integration.
Mechanical sub-assembly preparation — cable cutting and termination, harness routing and tie-down, connector crimping, and bracket assembly. 5S discipline maintained across all workstations.
PCBA, mechanical parts, displays, connectors, and cables assembled into the enclosure at Plant 2. Assembly follows work instructions derived from customer drawings. ERP tracks every unit from order to dispatch.
Ultrasonic welding for plastic moulded enclosures where applicable. Conformal coating applied selectively per customer specification. Enclosure sealing and integrity checks completed before test.
Functional testing and final inspection per customer test plan. Failed units flagged for rework. First pass yield tracked as a key quality metric — high FPY means fewer reworks and faster delivery.
Vacuum sealing, labelling, carton packing, and dispatch. Tape and reel available for module-level shipments. All shipments logged against the ERP order for full traceability through to delivery.
Vishesh's box build capability is active across sectors that demand certified quality, full traceability, and a single manufacturing partner.
Instrument clusters, EV BMS units, and control modules assembled under Vishesh's ISO 9001 and IATF 16949 certified quality system. Full PPAP-ready documentation and component-level traceability from board to finished unit.

Learn more →Inverter and UPS assemblies, power conversion units, and energy metering systems. Vishesh's in-house THT and wave soldering capability — at 6,000 boards per day — feeds directly into box build at Plant 2 which is a 20,000 sq ft facility.
Learn more →Ruggedised enclosure builds with traceability requirements. Vishesh's certified quality system with documented FMEA, work instructions, and ERP-tracked production satisfies the audit demands of defense supply chains.
Learn more →Single-source from bare board to finished product — Plant 1 handles PCBA and testing; Plant 2 handles mechanical assembly and box build. Both co-located at Vishesh's 45,000 sq ft Gottigere, Bangalore facility under one quality system.
IATF 16949:2016 certified — the same quality management standard your automotive and industrial customers require from their supply chain, covering both PCBA and box build assembly. Issued by TÜV Rheinland, valid to November 2025.
ERP-tracked production — live from April 2025, Vishesh's ERP system provides full order traceability from incoming material receipt through to dispatch, giving customers visibility and simplifying supplier audits.
Team with Fortune 1000 backgrounds — Vishesh's engineering and operations leadership brings experience from Schneider, Honeywell, Motorola, and BPL, bringing large-OEM process discipline to an agile mid-size facility.
Capacity available for dedicated line scale-up — Plant 2 has space allocated for volume ramp. Customers moving from prototype to production can scale within the same facility without re-qualifying a new vendor.
Vishesh handles everything from bare board to finished product at its Bangalore facility — under one certified quality system. Share your BOM or assembly drawing and our team will respond within 24 hours.
