Our Methodology

What is Component-Level Repair?

Most repair shops swap entire PCBs or send equipment back to the OEM — expensive, slow, and often impossible for legacy machines. Macro Controls engineers identify and replace only the exact failed components (capacitors, IGBTs, gate-driver ICs, MOSFETs, microprocessors) — restoring your equipment to factory spec at a fraction of the cost.
