Technical documentation and expert perspectives from the Kravzik engineering team. Covering the complete lifecycle from initial design validation to high-volume production excellence.

A supplier who plates your terminals but skips the JESD201 post-plating anneal will pass the incoming dimensional check. You discover tin whiskers only after field returns arrive. This checklist audits plating specification, pre-treatment protocols, and post-plating verification. Go through every item.

A PPAP package submitted with a compliance letter but without the Cpk capability study will pass the document checklist and fail the customer SQE review. This checklist audits dimensional capability data, material cert traceability, and testing standards documentation before the submission package leaves your supplier. Go through every document.

A terminal drawing that passes CAD review but lacks springback compensation data will drift out of tolerance by stroke 50,000. Your supplier catches it only at first-article rejection. This checklist audits flat blank layout, bend radii, and material grain alignment before die steel is cut. Go through every item.

A missed JESD201 anneal on your terminal lot triggers PPAP rejection, and you catch it only at the compliance audit. This checklist verifies DFM sign-off, material certs, and compliance docs before tooling cut. Go through the full audit.

A washing machine control board terminal passing factory testing fails after 2,000 cycles when the crimp joint relaxes. In this guide, you will learn cost-optimized material selection and UL 60335 compliance. Read the full guide.

An ECU stamped terminal passing testing at 25°C fails after 1,000 thermal shock cycles from -40°C to +125°C. In this guide, you will learn USCAR-2 contact stability and IATF 16949 PPAP. Read the full guide.
