2. For special requirements of the goods should be classified according to the requirements of management, to maintain normal temperature and humidity. Plastics and their products indoor temperature is generally maintained at 0-25 ℃, the relative humidity is not greater than 70%; radio components indoor temperature is maintained at 0-40 ℃, the humidity does not exceed 75%; rubber and their products room temperature is generally maintained at 0-25 ℃, the relative humidity is 45 -70%; anti-static area temperature is generally maintained at 10-30 ℃, relative humidity of 30-70%; petroleum products library temperature does not exceed 25 ℃.
3. RoHS "electrical and electronic equipment" (WEEE) means equipment whose normal operation depends on the generation, transmission, and measurement of electrical currents or electromagnetic fields, and which is designed for voltages not exceeding 1000V AC and 1500V DC. and electrical equipment does not contain lead, mercury, cadmium, hexavalent chromium, polybrominated diphenyl ethers (PBDE) and polybrominated biphenyls (PBB) six materials.
4. Warehouses should be set up with temperature and humidity meters. For the environmental temperature and humidity of the storage area, a person must be appointed to check and record the situation every day, and turn on the moisture-proof equipment every day according to the specific situation. For exceeding the standard, appropriate measures should be taken as soon as possible until the return to normal, the corrective measures taken should be recorded.
5. Warehouses should have certain conditions to maintain temperature and humidity, there should be cold curtains in winter, in and out of the warehouse should pay attention to the door, to prevent drastic changes in room temperature; summer to strengthen the warehouse ventilation and cooling measures.
6. Electronic components and PCB board moisture management
(1) incoming material for the vacuum packaging, incoming material itself has been marked with moisture-sensitive grade and the company's design and other aspects of the design of the important IC labeled with moisture-sensitive requirements or easy to oxidize the key pieces of three aspects of the material need to be vacuum-packed or packaged protection.
(2) The Procurement Department should strictly require suppliers of moisture-sensitive materials for standardized packaging, there are indeed special circumstances can not be standardized packaging or the company's internal inspection and check the reasons for the opening of the packaging of moisture-sensitive materials, by the company's organization to carry out vacuum packaging protection.
(3) the custodian of the procurement of vacuum-packed materials received need to confirm that the vacuum packaging with or without damage, with or without air leakage, with or without warning labels, etc., and the organization of the protection process. For vacuum-packed materials, need to be stored in the temperature and humidity controlled area.
(4) the warehouse of the production workshop to return to the remaining moisture-sensitive materials bulk, it is necessary to ensure that it is vacuum-packed, and check the vacuum packaging whether there is leakage, whether there is damage, whether the material is oxidized, etc., and only to meet the requirements to be allowed to receive, or you can ask the production workshop to re-packaging.
(5) The warehouse should keep the original vacuum packing state when issuing vacuum packing materials.
(6) for the storage of vacuum-packed materials, the custodian should be more than 5 kinds of daily spot-checking materials to confirm the conformity of its vacuum-packed condition, in the spot-checking of the materials found in the vacuum packaging has been leaking or broken and other conditions, the custodian should be unpacked to check the inside of the humidity card indicator status or the condition of the materials, if the humidity indicator in the RH30% above has become pink or has been obviously oxidized, then refer to the relevant departments to deal with. If the humidity indication has turned pink at RH30% or above, or has been obviously oxidized, then it will be referred to the relevant departments for processing.
