How to Connect to Terminal Clips to Heating Film > Notice

• 목록

There are four ways to connect a terminal clips to heating film.
RexVa is on "soldering method" principle.
The soldering method has the disadvantages of having to work with an experienced expert, but you should use this method for safety.
Even if the terminal clips are inevitably used, make sure that insert the film between the terminal clips and fix the terminal clips more than once to strengthen the bond between the heating film and terminal clips.
One of the following four methods is the soldering method, and the second method is to put the heating film between the terminal clips.
The third and fourth are not recommended.


[ How to Connect to Terminal Clips to Heating Film ]
1. Soldering Method

- Advantage
① The safest method
② There is no danger of overheating or sparking due to short-circuit of contact area by strong adhesive force at soldering area.

- Disadvantage
① Experienced professionals should work
② When beginner is working, installation time is increased

- Cautions
① The soldering is not too thick
② The insulation should be cut with a knife so that the solder side does not protrude and put into it


2. Put Heating Film between Terminal Clips

- Advantage
① It is most commonly used method in the following safe way
② Due to the area where the terminal and the copper foil touch is small and the bonding force between the terminal and the film is strong, low probability of overheating or sparking that short-circuit of contact area by strong adhesive force at soldering area.
③ Easy to install for beginner

- Disadvantage
① Electrical conductivity may be reduced. However, if the installation length of the film is less than 8m recommended by RexVa, there is no problem in heat generation

- Cautions
① Terminal clips should be pressed twice on the right side and the left side with a clipper so that the terminals are tightly bonded to the film


3. How to Insert Terminal Clips into Heating Film

- Advantage
① High electrical conductivity due to direct contact between the copper foil and the terminal clips of the heating film

- Disadvantage
① The most difficult way to do it
② When inserting the terminal clips, the adhesive side of the heating film may spread and air layer may be generated and then sparks may occur.

- Cautions
① Terminal clips should be pressed twice on the right side and the left side with a clipper so that the terminals are tightly bonded to the film.
② Make sure that the copper foil layer is between the terminals as shown in the picture.


4. How to Use the Eyelet

- Advantage
① Easy to install for beginner

- Disadvantage
① The contact surface between the islet and the copper foil is narrow, and a part of the total area of the copper foil is connected to the eyelet, resulting in lower electrical conductivity.
② The shortening strength of the eyelet and the copper foil is weakened over time, and short circuit is likely to occur and a spark may occur.
