Drone electronics
Flight controllers, 4-in-1 ESCs, power distribution boards, VTX modules, GPS units, gimbal boards and receiver modules.

Component-level repair,
Component-level repair,
not board swapping.
Most service centres replace the whole board. We find the failed component, remove it under a microscope and put a good one back. Cheaper for you, and far less electronic waste for everyone.
Scope
What comes across our bench.
If it has a printed circuit board and a fault, it is worth sending to us before you replace it.
RC & robotics boards
RC car ESCs, servo controllers, receivers, robot driver boards, motor controllers and sensor modules.
Mobile & tablet boards
Charging IC faults, no-power diagnosis, display and touch IC issues, backlight circuits and port replacement.
Laptop & computing
Motherboard power sequencing, DC jack and charging circuits, no-display faults and BIOS recovery.
Battery packs & BMS
LiPo pack rebuilds, cell balancing faults, BMS diagnosis and connector replacement, handled with proper safety controls.
Radio & RF equipment
Transceiver finals, PA sections, front-end protection circuits, display boards and control panels.
Bench capabilities
The work we actually do.
Removal and replacement of surface-mount components down to 0201 packages under
stereo microscope — resistors, capacitors, MOSFETs, regulators, connectors and
fine-pitch ICs. Includes broken pad repair and jumper wire reconstruction.
Controlled hot-air and preheat profiles for removing, reballing and reseating
ball-grid-array packages — processors, memory, power management ICs and
system-on-chip devices — with post-rework continuity verification.
Schematic and boardview-based fault finding using multimeter, bench supply,
thermal camera, oscilloscope and short-detection methods. We identify the failed
stage rather than guessing at replacements.
Reflashing bricked flight controllers and ESCs, DFU recovery, bootloader
restoration, EEPROM and SPI flash programming, and configuration restoration
after a failed update.
USB, JST, XT and FPC connector replacement, including pad reconstruction where the
original footprint has lifted or torn away.
Ultrasonic cleaning, corrosion removal, trace repair and protective recoating for
boards exposed to water, spray chemicals or field conditions.
Hand assembly of prototype boards, modification of existing designs, wiring
harnesses and bring-up support for student projects and startup hardware teams.

Service flow
From fault report to tested board.
01
Intake & fault report
You describe the symptom and what happened before it failed. Crash, short, failed firmware update or water — the history narrows the search considerably.
02
Diagnosis
Visual inspection under magnification, then electrical testing against the schematic to isolate the failed stage or component.
03
Estimate & approval
You receive the finding, the proposed repair, the cost and an honest verdict on whether repair is worth it. Nothing proceeds without your approval.
04
Repair
Component-level rework at an ESD-safe bench, using appropriate thermal profiles and genuine replacement parts wherever available.
05
Test & return
Powered testing, functional verification and — for flight electronics — bench motor and telemetry checks before the board is packed and returned.
Send us the fault before you send it to landfill.
Describe the symptom and we will tell you honestly whether it is worth repairing.
