1. The initial trial of SMT patch validation holds utmost significance. With accurate component specifications, models, and polarity directions in the first trial, the machinery will avoid misplacement of components in mass production. Correct alignment typically guarantees repeatability in mass production.

2. Various methods for conducting the initial trial are outlined here, tailored to diverse production needs in patch processing.

3. LCR measurement stands as one such method, apt for relatively uncomplicated circuit boards with fewer components, eliminating the necessity for reflow post-printing completion.
