METHOD OF MOUNTING
For normal use the varistor may be mounted on
printed-circuit boards or ceramic substrates by applying
wave soldering, reflow soldering (including vapour
phase soldering) or conductive adhesive in accordance
with CECC 00802 classification A. For advised
soldering profiles see Figs 4, 5, and 6.
