Matters needing attention
1. This product is packed with environmentally friendly materials,
50 pieces of small packaging, 200 pieces of large packaging;
2. Avoid storing the product in humid and high temperature
environment;
3. It should be stored in a non-erosive gas, otherwise it will lead
to oxidation of the tin layer and decrease of weldability.
Therefore, after opening the package should be used as soon as
possible
4. Working environment humidity ≦95%
5. Welding time as short as possible; Soak the tin liquid (Sn63
Pb37) at 230℃ to 5mm away from the CdS photoresistor body, and
maintain 3-5s.
6. Note that the lead welding position should be more than 4mm away
from the ceramic base.

Packing and Shipping:
Light Dependent Resistor Packaging and Shipping
Light Dependent Resistor (LDR) products must be handled properly to
ensure the best possible results. LDRs should be stored in a dry,
dust-free environment, and should not be exposed to extreme
temperatures or environmental conditions.
When shipping LDRs, they should be packaged properly using
air-tight, waterproof containers, or special shipping boxes. It is
also important to ensure that the containers are properly labeled
with the type of LDR, the shipping destination, and any special
handling instructions.
When receiving LDRs, it is important to inspect the package for
damage. If any damage is found, it should be reported immediately
to the shipper. It is also important to confirm that the product is
