03. Precautions during mounting –to- reflow

03-1. Mounters

We recommend that you select a multi-function mounter to mount connectors.
Even if you select a high-speed mounter, please use a multi-function head and load
control.

03-2. Precautions for selecting a pickup nozzle for

mounting connectors

Select a pickup nozzle with a pickup area that provides a theoretical lift force

10

times

greater than the connector’s weight.

Theoretical lifting force (gr) = Vacuum pressure (mmHG) /760
