CONNECTION VALIDATION VS STANDARD SOLDERING
WHY USE CONNECTION VALIDATION?
A Revolution in Soldering Starts with a Single Joint. Metcal’s exciting newest technology,
Connection Validation (CV) is integrated into the Robotic Soldering System. CV reduces solder joint
defects by validating the intermetallic compound (IMC) formation in a soldered joint and reduces
unnecessary dwell time by signaling to the system to move to the next solder joint in the automatically
after a good joint is formed. CV Soldering Cartridges work in conjunction with
SmartHeat
®
and
patented Chip in Cartridge technology. The time on each solder joint is calculated dynamically
based on the CV algorithm rather than a preset dwell time. This in turn will reduce solder joint defects
and lead to an improvement in quality while also mitigating risk. In addition, the
Chip in Cartridge
technology precisely calculates and displays tip temperature on a large color display, improving audit
compliance.
FLOW CHARTS OF SOLDERING PROCESSES
When determining which process, CV or Standard Soldering, is best for a given application, it
is best to understand the process flow for each process during a soldering event. Below are two
diagrams which breakdown when each of the settings within each process are used.
