BEST Inc. can solve several problems using this robotic hot solder dip technology including the following:

Gold Removal to meet  J-STD-001

Gold needs to be removed to reduce the risk of failure associated with embrittled solder.

Restoration of Solderability

Corrects finishes affected by oxidation, poor quality plating, foreign material, or post PCB removal.

RoHS Compliance

The hot tin solder dip process is used to remove the leaded alloy and replacing it with a RoHS compliant alloy.

Alloy Conversion Lead-free, Tin-Lead and Custom Solder Alloys Alloy Conversion Lead-free, Tin-Lead and Custom Solder Alloys

The flexibility of the BEST process and our equipment allows for refinishing to a wide variety of alloys to satisfy your requirements. Our process is a US Navy-qualified process as it removes 100% of the pure tin and replaces it with SnPb (tin-lead) to prevent tin whiskers. Parts can be processed per GEIA-STD-0006.

The typical robotic hot solder dip process consists of the following steps:

• De reel (if required)
• Pre inspection
• Bake (if required per J-STD-033)
• Masking (if required based on part geometries allowing for ingress)
• Robotic Hot Solder Dip
  • Load parts into fixture
  • Bring up program, initiate cycle
  • Parts into flux-programmable, insertion length
  • Parts out of flux
  • Dwell
  • Parts into solder dross wiped off programmable insertion length, time
• Cooling
• Cleaning
• Re reeling (if required)
