LPO uses low viscosity ‘hotmelt’ adhesives applied under low pressure. Using process specific moulding machines, the mould tooling is manufactured from aluminium to keep costs low and lead-times short.

For some applications LPO has replaced more complex, time consuming processes such as potting, where a separate housing is required and a two part moulding compound  is often used. In addition it gives off no toxic fumes. It is said to enable more complex mould designs and to be a cost effective method for protecting electronic assemblies. Stand A29
