Standoffs

A number of threaded standoffs are used. As with the screws and washers, be sure you use the correct size as

specified in the text. Standoff lengths are measured from end to end as shown in Figure 3. Standoffs threaded for

2-56 and 4-40 screws are used.

Figure 3. Typical Standoff.

Lock Washers

Two types of lock washers are used in the K3 (see Figure 4). It is important that you use only the type specified

and put the washers exactly where indicated. Failing to use the correct type may result in short circuits to nearby

circuit traces. Adding washers or placing the washers in the wrong position may cause parts to fail to fit together

properly.
