Ceramic Resonators (CERALOCK®) FAQ

Are there any points to be awere of when we take CERALOCK® off PCB for failuer analsys of CERALOCK®?

When a large heat stress is added to CERALOCK®, it may cause "depolalization" and electric function becomes poor or disappear.
So when the large heat stress is added to CERALOCK® by accident when you want to take it off from PCB, depolalization may occur and lead to the defect.

Therefore, when you take CERALOCK® off from PCB, consider the following issues.
  • Please keep the tip of soldering iron / spot heater away from CERALOCK®.
  • Please pay enough attention to ;

Hot air temperature of spot heater

Tip temperature of soldering iron

Pre-heating temperature and time

The recommendable soldering condition (by soldering iron) for CSTCR, CSTCE and CSTCC type is as follows.

Soldering iron: +350±5゚C, 5.0±0.5 sec.


take off

If you would like us to analyze CERALOCK® which had mounted on PCB, please send the whole PCB or cut out a part of PCB without taking CERALOCK® off from PCB.
