Automotive PCBA demanded more than modest competence. The circuits would serve ECUs and power modules—assemblies intolerant of voids beneath large-area components or uneven reflow across 2-oz copper. He had heard tales of factories that purchased inexpensive lines only to spend twice the sum on rework and warranty claims.
Correspondence with I.C.T commenced cautiously. Their response arrived promptly, not with glittering promises but with questions: board dimensions, heaviest component mass, monthly target, exact floor plan. From these they proposed a measured arrangement: I.C.T 5151 printer, Samsung DECAN S1 mounter, L8 reflow, AI-5146 AOI, loaders at each end—all sized to slip between obstacles while preserving process integrity.
December brought the engineer—courteous, methodical, unhurried. He measured twice where others might have measured once, adjusted conveyor heights to clear a low beam, recalibrated the oven’s zones until the profile showed less than ten degrees variance end to end. Training proceeded with the patience of a governess introducing young ladies to etiquette: operators learned to recognize when paste volume drifted, when a feeder jammed, when AOI flagged shadow instead of defect.
The trial run felt almost domestic—small batches moving smoothly, minor adjustments offered and accepted, coffee shared during pauses. By handover the proprietor’s manner had softened from polite reserve to genuine satisfaction. The line, once an uncertainty, now stood as quiet proof that reliability need not require vast acreage.
