Compare beryllium copper, phosphor bronze and stainless steel for stamped spring contacts: conductivity, strength, fatigue, springback, corrosion and cost.

A practical EMI shielding can design guide: material choice, seam and grounding design, aperture rules, wall thickness, retention features and testing.

How shielding effectiveness is measured, which test methods are used, what affects the result, and how to avoid common failures in stamped EMI cans.

A practical deep drawing design guide: draw ratio, punch and die radii, clearance, wall thickness, material selection, lubrication and annealing.

A troubleshooting guide to deep drawing defects: wrinkling, tearing, earing, springback, orange peel, galling and thinning, with practical countermeasures.

Compare deep drawn enclosures with stamped and welded enclosures on seams, tooling, cost, geometry, sealing, strength and lead time.

Dimensions were all in tolerance, yet the clips failed to rebound. The culprit was material: 301 stainless swapped for C5210 phosphor bronze, die compensation re-tuned, then 100k-cycle life testing.

Precision is measured layer by layer from first article to shipment: calipers for patrol checks, projectors for profiles, CMM for critical dimensions - gauges picked at 1/3 to 1/10 of the tolerance.

Same process on paper, completely different requirements. Die clearance, servo presses and CMM inspection draw the dividing line - and explain why tooling costs more but unit cost drops at volume.
