Bakelite Single Face Photographic Plate 10*15cm
simple photographic plate/bakelite/PP 7.5*10CM circuit board/light printing plates
Product Description
Specific production steps:
( A ) the original production : A first circuit with circuit design software to design , and then use the laser printer in a transparent, translucent or plain white paper printed underlay , inkjet printers clunky , but the quality is poor,
Dot matrix printer can not be used . B is available photoplotter or photographic film output basemap , this works best. C There is a thermal transfer paper appeared , the available heat transfer machine dedicated thermal transfer paper onto the map
Thus giving a basemap .
( 2 ) Crop: The light printing plates removed from the bag , first cut off the protective film dielectric paper knife , and then press the desired size saw or cutter cut a good circuit boards, in order to prevent poor adhesion , will be required Cuodao flash circuit board
Polished . The remaining light printing plates back into the bag and in a cold dark place. Note that when cutting can not be peeled off the protective paper to prevent scratching or defaced photosensitive surface . Electricity boards can also be used a knife to cut the upper and lower sides of the deep
