Abstract
Some implementations of the disclosure are directed to a solder preform, comprising: a solder alloy body, the solder alloy body comprising at least one opening; and a flux core embedded in the solder alloy body, the flux core comprising a thermochromic indicator, wherein during reflow soldering, the flux core comprising the thermochromic indicator is configured to flow out of the at least one opening of the solder alloy.
Claims20
A solder preform, comprising:
- a solder alloy body, the solder alloy body comprising at least one opening;
- a flux core embedded in the solder alloy body, the flux core comprising a thermochromic indicator, wherein during reflow soldering, the flux core comprising the thermochromic indicator is configured to flow out of the at least one opening of the solder alloy.
A solder ribbon, comprising:
- a flat solder alloy body;
- and
- a flux core embedded in the solder alloy body, the flux core comprising a thermochromic indicator, wherein during reflow soldering, the thermochromic indicator is configured to lose color as the solder alloy approaches its peak reflow soldering temperature.
A solder wire, comprising:
- a wire-shaped solder alloy body;
- and
- a flux core embedded in the wire-shaped solder alloy body, the flux core comprising a thermochromic indicator, wherein during reflow soldering, the thermochromic indicator is configured to lose color as the solder alloy approaches its peak reflow soldering temperature.
