DESCRIPTION! MEASUREMENTS! AND INITIAL DESIGN


2/13

$ltra%iolet Li"ht Bo& is a common 'rototy'e used by 'rinted circuit boardmanufacturers to de%elo' a customi(ed circuit in accordance with the 'attern'rinted on an acetate 'a'er. $nli)e old tradition of de%elo'in" a customi(ed'attern usin" ta'es* this 'rototy'e can actually enli"hten the circuit 'attern to a

'hoto+sensiti(ed PCB throu"h the use of ri"ht li"htin" system and of course* theacetate 'a'er.

,he construction of the said 'rototy'e can be home+made or customi(ed. ,he$ltra%iolet Li"hts -$# can be 'laced into a wooden 'rototy'e bo&* or sim'ly in ametal+related solid material.

M"#s$%"&"'s /ou cannot create a li"htin" e&'osure bo& without yourfluorescent li"hts or ultra%iolet li"hts. 0t is because* the starter holder -witho'tional transformer and either o'tioned li"htin" system will determine how lon"the base and co%er will be. $sually* the li"htin" system is commonly 'laced at

the to' for better 'erformance of de%elo'in".

$# Li"ht Bo&1 the dimensions for co%er and base* includin" the width* len"th* and the drawer.

D"s*+' ,he 'rototy'e is created throu"h a metal sho'* and the commonmaterial used for creatin" the bo& is made from a certain ty'e of stainless steel.
