According to the Japanese electronic circuit industry ,(JPCA) released statistical data to show, in April 2012 Japanese printed circuit board 's production fell 0.7% to 1.343 million square meters compared to same month last year ,it is the first decline within three months, the yield fell 6.6 percent to 46.369 billion yen, consecutive downward for two month. From January to April 2012, Japanese PCB production increased 2.3 percent to 5.712 million square meters, the yield declined 3.9 percent to 2,062.14 billion yen .In terms of the types, in April Japanese hard board (RigidPCB) production has an increase by 10.3 percent to 95.3 million square meters, showing growth for the third consecutive month ; yield increased 2.9 percent to 31.256 billion yen, for two months showing growth. Recession FPC (FlexiblePCB) production declined by 8.9% to 33.9 million square meters, ending with five rising trend; yield increased 2.7 percent to 6.818 billion yen, the fifth consecutive month showing growth. Module substrate's (ModuleSubstrates) production declined by 56.4 percent to 5.1 million square meters, the yield had a decline of 34.3 percent to 8.295 billion yen. Accumulated from January to April 2012, hard board production in Japan over the same period last year grew 6.5 percent to 3.961 million square meters., The yield decline of 2.1 percent to 1,346.25 billion yen; FPC production grew 10.5 percent to 1.476 million square meters, the growth of yield 9.7 percent to 28.342 billion yen; module substrate output declines of 48.0 percent to 27.6 million square meters, the yield decline 15.6 percent to 43.247 billion yen.
