1 引言 用于通讯和移动电话的总台的背板(BackBoard)已增加了要求。 一般来说,背板的特性是更厚的板和更大尺寸的板,如未来背板的尺寸将达到:30″×70″,而现在常规尺寸为21″×24″。 背板在制板钻孔比起常规在制板的钻孔将带来一系列困难和低的生产率。 本文将阐述背板钻孔的基本钻孔概念和合适钻孔的机床的特种功能。
1 Introduction The BackBoard for communication and mobile phones has added requirements. In general, the backplane features thicker boards and larger boards, with future backplanes up to 30 “x 70” in size and now the regular size is 21 “x 24”. Backplanes Boring holes in the system plate creates a series of difficulties and low productivity compared to conventional in-plate drilling. This article explains the basic drilling concepts for backhoe drilling and the special functions of the machine tool for the appropriate drilling.
