A new type of FR-4 material transparent circuit board brings joy to the LED glass screen industry chain
1: What is the composition of transparent FR-4 PCB made of? Transparent FR-4, transparent solder paste
2: Surface processing techniques can include OSP, immersion gold, electroplating gold, spray tin, and immersion tin
3: Transparent finished products can meet a transparency of over 90%
4: The main parameters for the high temperature resistance of transparent FR-4 are that the temperature can be the same as normal FR-4 material properties, with a tin immersion temperature of 220-250 degrees Celsius, three times in ten seconds, no foaming, no layering, and the relative dielectric constant is the same as most TG values of FR-4.
5: Transparent FR-4 can replace PET material, flexible FPC board, transparent PI material, organic board material 4: 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 costs higher than transparent FR-4 materials. In addition, LED network operators have high maintenance costs and are very prone to breakage. In long periods of hot weather, LED beads are prone to aging.
4: FR-4 transparent material has advantages in cost. Its transparency will be more than 90%. It can be heat-resistant, with high welding quality, and can meet the characteristics of traditional FR-4 materials. Therefore, selecting transparent FR-4 materials is the most ideal choice for transparent screen industry chain
