ultrathin FR4 PCB

Advantage for H-CELERITY

In 2014, H-Celerity PCB Limited put into operation two Full-automatic screen printing lines, two Full-automatic coating lines and three 1.55*0.85M Big Table-board LED Exposing Machine, giving the daily delivery capacity of backlight source circuit board of up to 2000-3000 square meters. Faced with customers’ requirements for the quality of ink color difference and reflectivity of backlight products, in order to ensure the quality, H-CELERITY has purchased advanced testing equipment such as color difference meter, reflectivity tester and ink film thickness tester for backlight source products. In order to further improve the reflectivity and color difference of ink, H-CELERITY has also developed special LED ink and OSP formula with ink manufacturers and OSP surface treatment venors. Now, the comprehensive reflectivity of high-reflective LED ink can be over 83, and OSP surface treatment can withstand high temperatures for three times, reaching a higher level in the industry. At present, the maximum size of LED board can be 1500*550MM. Now, H-CELERITY’s main customers include Opple, MTC, Yankon, Nation Star, Topstar, KTC, Philips and other well-known customers at home and abroad.

We  built  new prodcution line in 2018,mainly for ultrathin FR4 PCB,the thickness from 0.075-0.6mm,provide the reliable and slim solution in customized lighting products,Electronic handwriting,flex led display,micro motor,smart card and so on.
