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.
