Let’s tell you one way to check the trace quality<\/strong>\u00a0is good or not after developing of flexible circuits<\/strong>. After developing, even if some developing trace is dirty, or the base is long, is unable to check them out with a magnifying glass; but Cucl2 test is a non-destructive testing way. Testing methods are as follows:
\n1) First to clean the flexible pcb<\/a> surface after developing, for example:
\nAfter developing \u2192 acid washing \u2192 acid etching \u2192 acid\u00a0
\n2) in a 5% Cucl2 solution for 30 seconds, the best to swing liquid slightly, and use a sponge to remove small air bubbles on the board to invoid to affect judgments.
\n3) washed
\n4) drying
\n5) visual inspection
\nThe copper surface of normal developing will form a layer of gray and black oxide layer after handling.\u00a0 When the\u00a0 surface of flex pcb<\/a> with dry film glue, there will still maintain a bright copper color. This method can be tested if developing of flexible circuits<\/a> is good.<\/p>\n
