C. Drying
When drying cleaned assemblies, DO NOT exceed recommended temperature limitations. Excessive
temperatures may cause degradation of the connector used as a stabilizer during the soldering process.
D. Soldering Guideline
Manual 402--40 is available upon request and can be used as a guide in soldering. This manual gives
various flux types and characteristics, commercial designation, and flux removal procedures. A checklist is
included in the manual to aid in obtaining information pertaining to soldering problems.
3.6. Posted Contacts
Pin and socket contacts having 0.64 mm [.025 in.] square technology posted aft ends are available to fit
HD--20 connectors. Posts 3.18 mm [.125 in.], 4.78 mm [.188 in.], 10.80 mm [.425 in.], and 16.54 mm [.651 in.]
in length are offered, allowing a variety of mating or grounding options. When inserting posted contacts into
housings, be careful to hold the contact by the transition flange. See Figure 1.
3.7. Repair/Replace
Use Insertion/Extraction Tool 91285--1 (Instruction Sheet 408--9404) to remove individual contacts from
housings for replacement or for relocation to another housing cavity. Damaged or worn contacts may be
replaced provided there is sufficient slack, after restripping the wire, to insert the new contact.
DO NOT re--use damaged or worn contacts. Instead, replace them with new contacts and discard the old ones.
4. QUALIFICATION
No qualifications or approvals are required for HD--20 Precision Formed Contacts.
5. TOOLING
HD--20 Precision Formed Contacts can be terminated to wire using hand, semi--automatic, or automatic
crimping tools. Recommended tooling, and instructional material, is provided in Figure 7.
All hand tools and applicators include integral dies. The automatic machines that hold applicators are also
listed in the table along with related documentation.
The Model “K” AMP--O--LECTRIC Terminating Machine 565435--5 has been superseded by the Model “G” Terminating
Machine 354500--1 for new applications. For existing applications, the Model “K” is still recommended because of the
large number of installed machines.
