Component-level repair · Watrous, NM
A failed control board costs $1,200–8,000 to replace. Repairing it costs 10–25% of that.
Commercial HVAC, refrigeration, kitchen, and ag equipment goes down on a failed component soldered to a board the OEM has on backorder. Ship the board here instead. Bench diagnosis is $85 and comes off the bill when you approve the repair — free outright on a trade account. Standard turnaround is 1–3 business days with a 90-day warranty.

Capabilities
Five lines of work
One operator, one bench. Repair pays the bills; the rest is built on the same skill set.
Component-level diagnosis and repair of commercial equipment control boards — failed relays, burnt traces, dead switching supplies, cracked solder joints, blown drivers, corroded connectors. Most failures are in the power supply or the relays, not the microcontroller.
Embedded firmware on ESP32 and ARM, PCB schematic capture and layout, prototype bring-up, systems integration, and React / Node / PostgreSQL applications. You own every deliverable and all source on final payment.
CAD design and 3D printing for obsolete replacement parts, brackets, knobs, enclosures, and prototypes. Mail in the broken part or send photos and measurements. CAD at $75/hr; simple parts from $105 flat.
Your logo as a 3D-printed desk sign or wall plaque — raised, two-colour, or with recessed pockets for resin — and laser-engraved black aluminum business cards. Signs from $45; 25 metal cards for $65.

Tell me the equipment, the symptom, and the number silkscreened on the board. If it is not economically repairable, I will say so before you pay for shipping.
