Bending
Strength
more than 10%
1 second of bending for this PCB shall be
applied.
Completely immerse the capacitor in the
molthen rosin for 2s and then put it in the
10mm molthen solder with a temperature of
235±5℃(265±5℃)for 2(5)s. after that
pick it up, clean the solvent and inspect it
under 10x or more microscope.
