1）What is the Circuit Paper?<BR>
Circuit Paper is a kind of double-layer flexible circuit board。Its thickness is only 0.08-0.1mm。<BR>
2）Composition of the Circuit Paper?<BR>
Circuit Paper is composed of screen printing,base material, pads,holes, wires and cutting line ect.<BR><BR>
3）How to choose a circuit paper?<BR>
1/The pixel pitch of the original LED module needs to be consistent with the circuit paper;<BR>
2/The original LED bead specifications need to be consistent with the circuit paper;<BR>
3/Some products have differences between vertical and horizontal lamps (vertical lamps are more common, while horizontal lamps are less common); If the original LED module is a vertical lamp, the circuit paper for the vertical lamp should be selected.<BR>
2、Measurement method for the pixel pitch of LED module<BR>
1) Measure the horizontal dimension(W) of the LED module using a caliper ;<BR><BR>
2) Count the number(N) of LED lamp beads in the horizontal direction ;<BR>
<BR>
3) Calculation: Pixel pitch (P)=The module size (W)/The number of lamp beads (N)<BR><BR>
【Numerical accuracy to 0.000】<BR><BR>
3、Measurement method for LED bead specification<BR><BR>
1) Measure the horizontal dimension (X) of LED beads using a caliper;<BR><BR>
2) Measure the vertical dimension (Y) of LED beads using a caliper ;<BR><BR>
3) Calculation: LED bead specification=SMD (X) (Y);<BR>
