Estec designs, builds and revives the electronic cards running India's industrial, defense and commercial equipment — from PCB and power-electronics design through to repair and re-manufacture.
Most repair houses stop at troubleshooting. Our design team takes on the harder brief: rebuilding a board whose original manufacturer no longer exists, laying out a new multilayer card from scratch, or re-engineering a panel around parts that are still in supply — from requirement stage through to a fully tested board.
Design, layout or modification of any analog or digital PCB — our team works with you from the requirement stage to fully understand your exact specification.
No limit on number of layers or board size, and no restriction on component type — through-hole or surface-mounted.
We re-design around an equivalent part, matching pin configuration while maintaining or improving on the original functionality.
We support low-volume and prototype production requirements just as readily as full production runs.
Every board we design and manufacture is functionally tested and burned in before it ships.
The human-facing side of the same panel — front overlays and keypads designed to match the electronics beneath them.
Not every project arrives as a finished schematic. Often it starts as a functional need, a failing legacy board, or a block diagram on paper. Our concept design service takes that starting point and turns it into a producible, testable card — defining the architecture, selecting currently-available components, and planning the layer stack before a single track is routed.
Because the same engineers design, prototype and later repair these boards, manufacturability and long-term serviceability are considered from the very first decision — not bolted on at the end.
From simple single-sided cards to dense high-layer-count interconnects, we design and build across the full range of PCB constructions.
Single, double and multilayer rigid boards up to 24 layers — the workhorse of industrial, defense and commercial electronics.
Flex circuits for tight enclosures, moving assemblies and space-constrained designs where a rigid board won't fit.
Combined rigid and flexible sections in a single board — fewer connectors, higher reliability, and compact 3D packaging.
High-Density Interconnect boards with microvias and fine features for the densest, highest-performance designs.
When an OEM has vanished, drawings are lost, or a board is long out of production, we reconstruct the design from the physical card itself — recovering the schematic, netlist and layout so the board can be repaired, re-manufactured, or improved.
This pairs naturally with our re-manufacture service: once a legacy board is reverse-engineered, we can rebuild it around currently-available components and keep the equipment it serves in operation for years to come.
Beyond the board itself, our team develops the embedded firmware and application software that brings a design to life — microcontroller firmware, control loops, communication stacks and the PC-side tools that configure and monitor the product in the field.
A dedicated design capability in power electronics — from intelligent battery management to high-power IGBT and SMPS-based charging systems, engineered for industrial duty cycles and reliability.
Intelligent charge-controller electronics for AC- and DC-input charging systems, managing the full charge profile and protecting the battery across its life.
Cell-monitoring and protection electronics that keep a battery pack safe, balanced and long-lived — the intelligence layer between the cells and the charger.
Compact, efficient switch-mode power supplies for chargers and power converters, delivering tightly-regulated DC from a wide AC input range.
High-power charging and conversion systems built on IGBT switching for demanding industrial loads where robustness and current capability matter most.
Our engineers repair almost any type of printed circuit board or power supply module — bio-medical and analytical equipment, telecom, and a wide range of industrial, commercial, marine and defence electronics.
Around 90% of board failures come down to a single failed component. When that component can be identified, roughly 9 out of 10 faulty boards can be recovered — at a fraction of the cost of buying a new one.
The DATS & VI-trace families were engineered in-house to functionally test digital, analog and mixed-signal devices in-circuit — using the voltage/current trace method for passives that have no functional test of their own.
Our flagship in-circuit fault analyser, engineered in-house for repair labs and production floors. It functionally tests digital, analog, mixed-signal and mixed-logic devices in-circuit and out-of-circuit, and recovers faulty boards even with little or no schematic — using power-off VI signature analysis to check every passive and active component against a known-good board.
A high-speed, affordable in-circuit functional tester built for repair and maintenance labs. It tests both digital and analog devices in-circuit and compares passive and active components live against a known-good board using the VI Trace method — making fast fault-finding possible on boards with no documentation.
The same proven DATS5000 test engine in a compact 3U rack-mount chassis, ideal for benches and test racks where space is tight. It brings 48-channel functional and VI-trace testing, board learn/test and full VISA impedance testing in a rugged, integrated form factor.
A lower-cost entry point into the DATS5000 platform for smaller repair operations, without giving up the essentials. It offers 32-channel functional and VI-trace testing, 3-channel VI signature analysis and full board learn/test on both in-circuit functional test and VISA.
An economical in-circuit tester purpose-built for 3rd-party PCB repair houses working with 5V-powered ICs. It provides 28 digital source/sink channels, 2 guard channels and 2 VI-trace channels, with board learn & test and link detection for straightforward, reliable fault diagnosis.
A Manufacturing Defect Analyser for quick component and connectivity checks — resistance, capacitance, inductance, diode and zener testing, plus open/short detection to rapidly locate a faulty node. LabVIEW compatible for automated test setups.
A compact, battery-powered handheld VI Trace tester with two simultaneous channels that stores up to 40 traces. With no external controller required, it is ideal for field diagnostics and quick bench comparisons using the known-good-board method.
A family of power-on in-circuit and power-off VI-trace testers that pair with Android tablets and phones — including the mVI-2 handheld. Affordable and truly portable, they let field technicians fault-find complex boards with no circuit knowledge using the comparison method via an Android app.
Purpose-built systems for teaching labs and dedicated verification: the Educational PCB Test System teaches out-circuit, in-circuit functional test, board learn/test and interactive VI trace hands-on, while our open/shorts and cable-harness testers provide fast continuity and short-circuit checks against a known-good reference.
A dedicated product line for the elevator industry — from in-cabin multimedia displays and Magic Mirrors to indicators, safety communication, control boards and spares.
In-cabin infotainment screens that show HD advertising, images and video, live weather, news and messages — with a mirror-surface option for a premium cabin finish.
Largest standard cabin display.
Shows floor number and travel direction.
Cabin and landing push-button panels.
Display integrated behind a mirror surface.
