Hot Solder Dip

Hot Solder Dip Services Tinning Services

Criteria Labs can refurbish your aged components and/or refinish your components by converting them from lead to lead free or from lead free to lead through hot solder dip.  Our expert team runs both fully automated and manual hot solder dip to ensure we meet the unique requirements for every component.  We are ISO, ANSI and EIA Certified.

Why Hot Solder Dip?

Hot Solder Dip changes the lead finish for a component to prevents tin whisker growth, increase solderability and solder strength.  A part is precisely “dipped” into a bath of molten material, creating a reaction and thereby coating the leads with Tin-lead (Sn-Pb) or tin-silver-copper (SAC-305).  This is an important process in the manufacture of electronic goods in high reliability environments.

Criteria Labs has the experience to adapt the hot solder dip process to each unique component.  With high volume of similar parts, we create standardized fixtures and specific profiles to ensure parts the highest level of repeatability, precision depth and dwell time in the bath.  We map each step in the process, flux, preheat, dip and cleaning to ensure every part is the same.

For low part volume, where the needs are different, our expert team creates a streamlined setup to reduce risk and changeover errors to maximize quality and minimize cost.  Our operators are able to more quickly change over specific part profiles from one set of requirements to another.

We meet all the requirements for:

  • GEIA-STD-0006
  • ANSI-J-STD-002
  • JESD22
  • Mil-STD-202
  • Mil-STD-883
