This section describes the methods and requirements for solderability testing. Solderability of printed boards verifies the state of the printed
board expected during assembly. Solderability testing is performed on both the surface and PTHs. IPC-J-STD-003 describes in detail the dif-
ferent solderability tests as shown in Table 5-1:
本节介绍了可焊性测试的方法和要求。印制板的可焊性测试是为了验证印制板在组装时的可焊性。在板的两面和镀覆孔内实施可
焊性测试。IPC-J-STD-003详细地介绍了各种不同的可焊性测试，表5-1列出了各种可焊性测试方法。

Along with the solderability method, the user shall specify as part of the purchase order agreement, the required coating durability. The fol-
lowing are guidelines for determining the needed level of coating durability, not product performance classes. Durability conditioning and
solderability testing shall be performed per IPC-J-STD-003.
Coating Durability categories:
Category1–Minimum Coating Durability; intended for printed boards which will be soldered within 30 days from the time of manufac-
ture and are likely to experience minimum thermal exposures.
Category2–Average Coating Durability; intended for printed boards likely to experience storage up to six months from the time of manu-
facture and moderate thermal or solder exposures.
Category3–Maximum Coating Durability; intended for printed boards likely to experience long storage (over six months) from the time
of manufacture, and may experience severe thermal or solder processing steps, etc. It should be recognized that there may be a cost premium
or delivery delay associated with printed boards ordered to this durability level.
The test specimen shall be a representative coupon, a portion of the printed board being tested, or a whole board if within size limits, such
that a immersion depth defined in the individual method is possible. Sample holes should be selected at random.
除了可焊性测试方法以外，用户还应当在采购协议中规定所要求的涂覆层耐久性。下面是确定所需涂覆层耐久性类型的指南，但
它不是产品性能等级。应当按IPC/J-STD-003的规定完成加速老化和可焊性测试。
涂覆层耐久性分类：
1类 – 最低水平的涂覆层耐久性。指制造完工后30天内要焊接的印制板，可能会暴露于最低程度的热环境中。
2类 – 一般水平的涂覆层耐久性。指制造完工后经过6个月以内贮存的印制板，可能会暴露于中等程度的热或焊接环境中。
3类 – 最高水平的涂覆层耐久性。指制造完工后经过长时间（6个月以上）贮存的印制板，可能会经历严苛的热环境或焊接工序
等。但应该注意到，采购该类印制板会增加额外成本、延长交货期。
测试样品应当为具有代表性的测试附连板、被测试印制板的一部分，或如果尺寸在限定范围内、以至可以达到测试方法规定的浸
焊深度，也可用整块印制板。试样的样品孔应该随机抽取。
