Diagnose first. Then repair.
We're building the tools that help you find the real fault - before a single part gets replaced. Free hardware tests from working board-level technicians: they run in your browser and nothing is uploaded.
What guessing does to a board
- Lifted pads and torn traces. Every chip removal takes the board to soldering temperature; pads under the chip can lift, fine traces can tear.
- Weaker layers. The fibreglass layers can blister or delaminate, especially after the board has already been heated before.
- Brittle joints. Each reflow thickens the brittle intermetallic layer inside the solder joints, so they crack sooner.
- Damaged neighbours. Chips and tiny capacitors next to it are heated too - their joints reflow and capacitors can crack from the thermal shock.
One diagnosed repair = one heat cycle on one part. A guessing repair can mean three or four. Sources: intermetallic growth over multiple reflows, IPC-7711/7721 rework damage.
E-waste in numbers
Keeping every smartphone in the world in use for one more year would save as much CO₂ by 2030 as taking 4.7 million cars off the road. Sources: UN Global E-waste Monitor 2024 (ITU / UNITAR), Junkyard Computing (manufacturing share), Carbon Trust.
What the right diagnosis saves
A dead board almost always has one fault: one shorted part, or one missing power rail. Measuring finds it. Guessing replaces chips until something works.
A shorted capacitor costs cents. Swapping a charging chip, a processor or the whole board "to see" costs hundreds - and often isn't the fault.
Every device powers on in a fixed order. Measuring where that order stops points to the stage at fault - no waiting for parts you didn't need.
Repairing only the faulty part keeps the board close to factory condition, so the device keeps working for years instead of coming back.
