FR-4 ultra-thin transparent single double multi-layer circuit board, transparent circuit board, transparent PCB, transparent FPC

1: What is the composition of transparent FR-4 and transparent solder mask made of transparent FR-4PCB material

2: Surface processing techniques can include OSP, immersion gold, electroplating gold, spray tin, and immersion tin

3: FR-4 transparent finished products can meet a transparency of over 90%

4: The main parameters for the high temperature resistance of transparent FR-4 are the same as those of normal FR-4 materials. The immersion temperature is 220-250 degrees Celsius, three times in ten seconds, without foaming or layering. The relative dielectric constant is the same as the basic TG value of FR-4. The thickness of FR-4 transparent material can meet the minimum requirement of 0.10mm ± 10%, and the thickness can reach 5.0%, with a dielectric constant of 4.1;

5: FR-4 copper has 0.5OZ, 1OZ, 15OZ, 2OZ, and the thickest copper can reach 5OZ (175um)

6: Transparent FR-4 can replace PET material, flexible FPC board, transparent PI material, and organic glass material

1: The filling temperature of PET material can only meet 80-120 degrees Celsius

2: The cost of transparent PI material is several times higher than that of transparent FR-4 material.

3: Tempered laminated glass has complex processing techniques and higher costs than transparent FR-4 materials. At the same time, LED network operators have high maintenance costs and are very prone to breakage. LED beads are prone to aging under prolonged high temperature conditions.

4: The cost of FR-4 transparent material is dominant, and the transparency will reach over 90%. It can be heat-resistant, with excellent electric welding, and can meet the performance of traditional FR-4 materials. Therefore, selecting transparent FR-4 materials is the most ideal choice for transparent screen industry chain.
