\nJanuary 2019.
\nUsing a manual toaster oven. Pre-heat to ~180\u02daC. Place board on a riser in center of oven. Let pre-heat for 2 minutes. Then increase temp. Temp reaches 210\u02daC – 220\u02daC in 2 – 2.5 minutes. Remove from oven. Using 63% Sn \/ 37% Pb solder paste.<\/p>\n","protected":false},"excerpt":{"rendered":"
