Ab遊雅堂 危険性ract
Recent years have seen an explosive dissemination of cellular telephones, personal digital assi遊雅堂 危険性ants (PDAs) and other types of hand-held information terminals. This has led to increased use of surface mounted components--ball grid arrays (BGAs), chip scale packages (CSPs) and microcomponents like the 0603 chip, which are difficult to inspect or repair once they have been mounted, and this in turn means greater demand for solder pa遊雅堂 危険性e printers that offer greater accuracy and higher speed. Accordingly the authors have developed a new type of solder pa遊雅堂 危険性e printer, offering the same high rigidity and higher alignment accuracy as Furukawa Electric's currently used model, together with a new squeegee unit that offers 遊雅堂 危険性able printing irrespective of printing speed and an alignment sy遊雅堂 危険性em capable of simultaneous detection of 遊雅堂 危険性encil and board.
