This part is the 14th part of GB/T 4937.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This section uses the translation method equivalent to IEC 60749-14.2003 "Semiconductor device mechanical and climatic test methods Part 14.

Lead end strength (lead robustness).

1 Scope

This part of GB/T 4937 specifies several different test methods for determining the robustness of the lead/package interface and leads. when

The board assembly error caused the lead to bend, and this test was performed in order to reassemble the lead reshaping process. For hermetic sealers

It is recommended that the seal test be carried out in accordance with IEC 60749-8 after this test to determine whether the stress applied to the lead end also causes a seal.

Bad effects.

Each of the test conditions in this section is destructive and only applies to the qualification test.

This section applies to all through-hole mounting devices and surface mount devices that require user lead forming.
