Vapor Phase Solder Reflow Jig for Chip Alignment Stability

The patent introduces a guide structure as an intermediary element between the condensation liquid and the semiconductor chip. This guide structure channels the condensation liquid along predetermined paths, preventing direct contact with the chip body that would cause misalignment, while still allowing the liquid to fulfill its lubrication function for smooth chip placement.

The guide structure provides localized control over condensation liquid distribution. By creating specific flow paths and contact regions, the liquid is directed only where needed for lubrication, rather than freely contacting the entire chip surface. This localized management maintains alignment precision while preserving the beneficial heat transfer and lubrication effects.

The guide structure serves as a mediator that enables controlled lubrication. It allows the condensation liquid to reach the sliding interface between the chip and substrate, maintaining ease of placement, while simultaneously constraining the liquid to predetermined paths that prevent unwanted lateral forces causing misalignment.

The guide structure is pre-configured with specific flow paths and contact regions before the soldering process begins. This preliminary arrangement ensures that when condensation liquid forms, it automatically follows the predetermined safe paths, preventing misalignment before it can occur during the chip placement operation.
