ABSTRACT:
A surface mount technology measurement and lead formation system provides high precision bending and trimming of offset leads for both two and four sided circuit components. A total form height includes a pair of horizontally adjustable support rails which support the leads of a component. A precision, linear displacement measuring device engages the body of the electronic component and provides a digital indication of the total form height of the leads of the component. The lead forming apparatus has a total form height adjustment mechanism through which the total form height of the leads of the component are controllably bent and trimmed. The total form height of the leads is preset by an operator, who manually adjusts a form height setting anvil, a control dial for which is coupled to an associated digital readout gage which conforms with the same units of the digital readout gage of the total form measuring device. The lead forming apparatus comprises upper and lower support platens upon which bending and trimming tooling elements are mounted.
