Inductance coil in our lives is applied more and more widely, but we in use may not be pay great attention to the slightly sentimental inductance coil requirements on the environment, to the outside world.
1 storage conditions
In order to maintain the solder ability of the end face electrode:
(1) the conditions of temperature and humidity are less than 40 degrees Celsius and 70% RH.
(2) the proposed ceramic chip inductor is best available for use within 6 months.
(3) packaging materials should avoid chlorine and sulfur environment.
2, Pattern Land design
The design of welding base of the electrode should be able to achieve good welding paint and reduce the movement of components in the welding process. The following is the most common design for welding general ceramic size in wave soldering and reflow. These designs are as follows:
(1) the width of the welding mat is the same as the width of the element. Reduction to 85% of the width of the element is allowed, but the reduction of more is not wise.
(2) welding bedding and components of the bottom of the overlapping 0.5mm.
(3) for the purposes of back welding, the welding base extends out of the element 0.5mm; wave soldering is more than 1.0mm.
(4) component spacing:
These are all we need to pay attention to the use of inductance coil, know that we can better play the role of the inductor coil.
