Steel mesh

The utility model relates to a spare part equipment technical field especially relates to a steel mesh, steel mesh including be used for with printed circuit board on the corresponding first portion of welding position with be used for with printed circuit board on the corresponding second portion of non - welding position, set up the steel mesh mouth on the first portion, the second portion is real core plate column structure. Do not open the steel mesh mouth on this second portion for the tin cream is difficult to mobilely to the position that need not weld electronic components, just also can not lead to electronic components the problem that became invalid to appear. Consequently, this steel mesh can improve electronic components's reliability. 本申请涉及零部件组装技术领域，尤其涉及种钢网，所述钢网包括用于与印制电路板上的焊接位置相对应的第部分和用于与印制电路板上的非焊接位置相对应的第二部分，所述第部分上开设钢网口，所述第二部分为实心板状结构。该第二部分上不开钢网口，使得锡膏不容易流动至不需要焊接电子元器件的位置，也就不会导致电子元器件出现失效的问题。因此，该钢网可以提高电子元器件的可靠性。
