Background
In 1998, the European Community (EC) issued the directive (67/548/EEC) on its 25th council concerning the adaptation to technical progress, on which the cobalt chloride was lined into one of the dangerous substances possibly causing cancer. Though the EC issued it, it was not forbidden formally.
With the technology improvement, people has more concerns of health and safety and higher requirements of environmental protection. Most of the integrated circuit manufacturers agreed that if the traditional humidity indicating method may cause cancer, then it is not applicable, and it shall be eventually replaced by Cobalt-free product.
Then the EC environmental regulation 2004/73/EC came into force, in which cobalt dichloride is listed as a banned material for using.
After several years of effort, TOPSORB has developed Humi-Watch+, a new generation of HIC, which is cobalt-free humidity indicating card of high precision, adapting to the new EC standard.
Features:
* Cobalt-free, Cl-free, environmental-friendly, comply with EC standard
* Easy to use; easy to read; quick to judge humidity value
* High precision of humidity-sensitivity;
* Reusable (after drying)
International/national quality standard.
* 2004/73/EC(EC regulation)
* GJB2494-95 (P.R.C. Military standard)
* MIL-I-8835A(U.S.A Military packaging standard)
* JEDEC(Standard of Joint Electron Device Engineering Council)

Advanced Production Technology of HIC
Up to now, most domestic suppliers of HIC in China are using burette by hand to drop the solution onto the cards. It is very rough and inefficient with unqualified products at high percentage. It is hard to control the strength precisely by hand when dropping. If no enough dropping, it will not cover full inside the circle print. If too much dropping, it will overflow the circle print.
We produce HIC by automatic machine. Our production efficiency is ten times to hand dropping. What is more, the size and strength of dropping is very precise, perfectly fitting the print circle. It has absolutely overcome the difficulties of uncontrollability of hand dropping. |
