Target Condition - Class 1,2,3(⽬标条件 - 1,2,3级)
• The surface of the solder mask is uniform in appearance and is
firmly bonded to the printed board surfaces.
• 阻焊膜表面外观均匀并牢固地粘附在印制板表面。
Acceptable - Class 2,3(可接受条件 - 2,3级)
• No evidence of solder mask lifting from the printed board prior to
testing.
• After testing in accordance with IPC-TM-650, Method 2.4.28.1,
the amount of solder mask lifting does not exceed the allowable
limits of the IPC-6010 Series.
• 测试前没有阻焊膜从板面上起翘的迹象。
• 按照IPC-TM-650测试方法2.4.28.1测试后,阻焊膜的脱落量
未超过IPC-6010系列标准规定的允许限值。
Acceptable - Class 1(可接受条件 - 1级)
• Prior to testing, the solder mask is flaking from the printed board
base material or conductive pattern surfaces and the remaining
solder mask is firmly bonded. The missing solder mask does not
expose adjacent conductive patterns or exceed allowable lifting.
• After testing in accordance with IPC-TM-650, Method 2.4.28.1,
the amount of solder mask lifting does not exceed the allowable
limits of the IPC-6010 Series.
• 测试前有阻焊膜从印制板基材或导电图形表面剥落,但其余
阻焊膜牢固地粘附在板面上。缺失的阻焊膜未暴露相邻导电
图形或未超过脱落的允许值。
• 按照IPC-TM-650测试方法2.4.28.1测试后,阻焊膜落脱的量
未超过IPC-6010系列标准的允许限值。
Nonconforming - Class 1,2,3(不符合条件 - 1,2,3级)
• Defects either do not meet or exceed above criteria.
• 缺陷不符合或超出上述要求。
