characteristics unless the following factors are appropriately
checked; the size of land patterns, type of adhesive, amount
applied, hardening temperature and hardening period.
Therefore, it is imperative to consult the manufacturer of the
adhesives on proper usage and amounts of adhesive to use.
Precautions
