PRECAUTIONS DURING INSTALLATION
1) Fixing fiber optical transceiving module
Insert the fiber optic transmitting module HKTX179S into the printed circuit board to fix the module to the board.
¡Solder the fixed pin at 260 or less within 5 seconds.
2) Soldering
Optical modules use semiconductor devices internally. However, in principle, optical modules are optical components.
At soldering, take care that flux dose not contact the emitting surface or detecting surface. Also take care at flux
removal after soldering. Some optical modules come with protective cap. The protective cap is used to avoid
malfunction when the optical module is not in use. Note that it is not dust or waterproof.
As mentioned before, optical modules are optical component. Thus, in principle, soldering where there may be flux
residue or flux removal after soldering is not recommended. GOOD TAKE recommends that soldering be performed
without the optical module mounted on the board. Then, after the board is cleaned, solder the optical module manually.
Do not perform any further cleaning. If the optical module cannot be soldered manually, use non-halogen (chlorine-
free) flux and make sure, without cleaning, there is no residue such as chlorine. This is one of the ways to eliminate the
effects of flux. In such a case, check the reliability.
3) Solvent
When using solvent for flux removal, do not use a high acid or high alkali solvent. Be-careful not to pour solvent in the
optical connector ports. If solvent is inadvertently poured there, clean with cotton tips.
4) Protective cap
When the fiber optic transmitting module HKTX179S is not in use, use the protective cap.
5) Input voltage
If a voltage exceeding the maximum rating value (Vcc+0.5V) is applied to the transmitter Input, the internal IC may
degrade causing some damage. If excessive voltage due to surge may be added to the input, insert a protective circuit.
