SMT Assembly at Vishesh, Bangalore
Surface mount technology (SMT) is the process of placing and soldering electronic components directly onto the surface of a printed circuit board — the dominant assembly method for modern electronics. Vishesh operates three dedicated Siemens SMT lines from its 45,000 sq ft facility at Gottigere, Bangalore, with a combined capacity of 206,700 CPH and full component capability from 0201 passives through to BGA, LGA, CSP, and 0.3mm fine pitch QFP packages.
Vishesh's SMT assembly services are part of a fully integrated electronics manufacturing services operation — covering everything from incoming material inspection and solder paste printing through to reflow, AOI, and functional testing — under a single ISO 9001:2015 and IATF 16949:2016 certified quality system, issued by TÜV Rheinland. SMT assembly at Vishesh is available for both prototype quantities and volume production, for OEMs across defence, automotive, industrial, and IoT sectors.

Component Range
0201 passives through to 0.3mm fine pitch QFP, BGA, LGA, and CSP packages. All standard SMD package types supported across all three lines.
PCB Complexity
PCB complexity up to 16 layers. Both single-sided and double-sided SMT assembly. PCB assembly services including mixed SMT and THT available from the same facility.
Wave Soldering
In addition to SMT, Vishesh's wave soldering line handles through-hole components at 6,000 boards per day (100mm length), supporting mixed SMT and THT assemblies within a single production flow.
SMT Process
Every SMT assembly at Vishesh follows a documented, audit-ready process — from solder paste printing through to inspection and handover to the next stage.
Solder paste is applied to the PCB using a stencil printer.
- Automated stencil printing for consistent paste deposit
- Paste volume and alignment verified before board advances
Solder paste inspection (SPI) immediately after printing.
- Automated SPI verifies paste volume, area, and offset
- Boards with paste defects are flagged before component placement
High-speed automated component placement across all three Siemens lines.
- Combined placement capacity of 206,700 CPH
- Fine pitch down to 0201 passives, 0.3mm QFP, BGA, LGA, and CSP
Visual inspection on the conveyor before boards enter the reflow oven.
- Component placement and orientation verified
- Missing or misaligned components corrected before reflow
Lead-free reflow soldering in multi-zone reflow ovens.
- Vectronics 9-zone (Line 1), OmniFlo 7 (Line 2), Omniexcel 7 (Line 3)
- RoHS-compliant lead-free solder process
Automated optical inspection (AOI) post-reflow on Lines 1 and 2.
- Solder joint quality, component presence, and polarity checked
- X-Ray inspection available for BGA and critical components
In-house rework capability for solder defects and component replacement.
- BGA rework via ZM-R7220A station on Line 3
- Manual rework for other defect types before re-inspection
Passed boards advance to the next stage of the assembly process.
- THT insertion and wave soldering for mixed assemblies
- Functional testing, conformal coating, or box build as required
