we are E-Rich technology CO.,Ltd. located in the NO.6 hauxi 2nd road,baxin villiage ,Henggang town ,longgang discrict,Shenzhen city,china. we specilizing in manufacuring many klinds of PCB board for 7years,now we have 400staffs ,and 6000 square meter workshop.the capability is over 10000 square meter per monthand we have cooperate with some factories.
we can manufacture these PCB board:
all the PCB board is rigid ,and single-sided ,double-sided .4-12layer PCB board,all the surface finishing included OSP HASL /HASL lead free,ENIG,immersion (gold,silver,tin) gold-plated and alum base board.Our profiling include punching/rounting /V-cut /beveling. we can manufacture the board thickness 0.4-1.8mm,copper thickness 1-6OZ. process size 1cm*1cm--58cm*58cm. min BGA location 0.35mm. min solder mask opening 0.075mm,min solder mask bridge 0.13mm.
all the PCB board are widely used in the digital ,GPS,phone,computer,household,LED ,electronic applicances ,power supply mechine,medical equipment and so on.
manufacturing mechine: we have digital controlled driller, scrubbing machine,exposure machine, laminator machine.developing machine,digital controlles fraise machine.manual silkscreen machine, two-door oven,processor,photoplotler,tester,probe terster. |
