1. SCOPE
1.1. Content
This specification covers performance, test s and quali ty requirements for the Tyco Electronics Surface|Mount Matched I mpedance Connector (MI CTOR) for board to board applications using two design
sty les, right angle and vert ical. These two piece connector designs accommodate a vari ety of printed
ci rcuit board thicknesses. Plug assemblies are loaded with .008 inch thick MICTOR cont acts whi ch mate
with hermaphroditic contacts in the receptacle assembly. Both plug and receptacle assemblies are
available in signal counts of 38 t o 266 position in 38 pin incr ements for .025 inch centerline.
1.2. Qualification
When tests are perfor med on the subject product line, procedures specified in Figure 1 shall be used.|Al l i nspections shall be performed using the appli cable inspection plan and product drawing.
1.3. Qual ification Test Resul ts|
Successful qualification testing on the subject product line was completed on 13Dec98. The|Qual ification Test Report number for this testing is 501-252. This documentation is on file at and|available f rom Engineering Practices and Standards (EPS).|

4. QUALI TY ASSURANCE PROVISIONS
4.1. Qual ification Testi ng
A. Sample Selection
Samples shall be prepared in accordance wi th applicable Instruction Sheets and shall be selected
at r andom from curr ent production. Test groups 1, 2, 3 and 5 shall consist of 3 mated pairs (plug
and recept acle) of vert ical and right angle assemblies. Samples shall be mounted on . 062 inch
thick pri nted circuit boards. Housings shall be full y populated with signal contacts and bus bars.
Test group 4 shall consist of 5 mated pairs (plug and receptacle) of vert ical and right angle
assemblies. Housings shall be fully populat ed wit h signal contacts and bus bars and shall not be
mounted on printed ci rcuit boards.
B. Test Sequence
Qual ification inspection shall be verified by testing samples as specified in Figure 2.
4.2. Requal ification Testi ng
If changes significantly affecting form, fit or function are made to product or manufacturing process,
product assurance shall coordinate requalification testing, consisting of all or part of original testing
sequence as deter mined by development/product, quality and reliability engineering.
4.3. Acceptance
Acceptance is based on verification that product meets requirements of Figure 1. Failures attributed to
equi pment, test setup or operator def ici encies shall not disqualify pr oduct. When product failure occurs,
corr ective action shall be taken and samples resubmitted for qualification. Testing to confirm corr ective
action is r equired before resubmittal.
4.4. Qual ity Conformance Inspection
The applicable quality inspection plan will specify sampling acceptable quality level to be used.|Di mensional and f unctional requirements shall be in accordance w ith applicable product drawing and
this specif ication.
