hanghai Xie Yin electronic circuit Co.,Ltd. is a company specialized on production of sing/double PCB. Located in Shang Hai China.  Currently we have developed FR5 high-temperature-resistant PCB, TG can reach as high as 170 degree which provides working capabilities on wider temperature range and longer usage in -60 degree--170 degree environment.  Meanwhile, we were awarded the UL(E301969) certification on FR5 PCB with 150 degree MOT as the key. Our PCB offers good reliability with better heat-resistance and mechanic intensity, lower distensibility of Z-axis, especially use in automotive electronical system???ower supply etc.
