求翻译：自2012年底起,PCB皆已要求廠商打上生產週期(如圖1), 但此台機器RV-0356的PCB無生產週期(如圖3), 故可判斷PCB是舊版本且是2012年底前製造的.是什么意思？

Since the end of 2012, PCB manufacturers have switched request marked the production cycle ( Figure 1 ) , but this machine RV-0356 of PCB -free production cycle ( Figure 3 ) , it can determine the PCB is an older version and are manufactured before the end of 2012

Since the end of 2012 since, PCB all requested the manufacturer to get production cycle (as shown in Fig. 1), but this machine RV-0356 PCB non-production cycle (as shown in Fig. 3), therefore may judge PCB is the old edition is precisely at the end of 2012 before, makes.

From 2012 year's end, PCB all has requested the manufacturer to get the production cycle( like chart 1), but this machine RV-0356 PCB non-production cycle( like chart 3), therefore may judge PCB is the old edition is precisely before 2012 year's end makes.

Starting from the end of 2012, and PCB, have also been asked to put on the production cycle (Figure 1), but this machine is RV-0356 the PCB production cycle (Figure 3), it can determine the PCB is made in older versions and is before the end of 2012.
