Wire-to-board system improves process capability and reliability

By Alex Pluemer, contributing writer

Molex claims the industry’s first SMT
potting wire-to-board connector system with the introduction of the Spot-On 1.5 and 2.0.  Molex believes the new potting system will
provide increased processing capability and mechanical reliability in home
appliances such as washer/dryers, stoves and air conditioners.

The Spot-On
connector system utilizes SMT-type potting connectors in conjunction with
center PCB nails to absorb the stress caused by temperature fluctuation during
operation, thereby reducing cracking in the soldering.  A potting sealant protects against water
damage while the potential for latch failure is diminished by an inner positive
lock design.


SMT mounting tails on each Spot-On connector save time and effort during
assembly and a polarized, color-coded receptacle housing simplifies the
wire-mating process.  All single-row and
double-row connectors also feature a retainer for more secure insertion of the
crimped terminal.

The Spot-On
Connector System provides 1.0 to 3.0 A of current and up to 36 available
circuits, and the 1.50-mm and 2.00-mm pitch makes it smaller and more space
efficient than its predecessors.
