For example: the A1 type of carrier plate of the adhesive + quality figure is shown as: CTIs-034FB/T 9239
The terminal block of talc AI type is as follows:
H—034JB/T9239
Part: Other fields listed in this standard shall be in accordance with the requirements agreed upon by the user and the manufacturer. The requirements shall be in accordance with the provisions of this standard. 4 Technical requirements
The terminal block shall be flat, smooth and complete, and shall not have defects such as cracks, melting, smoke, blockage, obvious bubbles, spots, etc. 4.2 Dimensions
The dimensions and tolerances of the wiring board shall comply with the provisions of 3.2.1. 4.3 Water absorption
The water absorption of the wiring board shall not exceed 0.2%. bzxz.net
44 Bending resistance (breaking)
The bending resistance of clay wiring board shall be 500N: the bending resistance of talc wiring board shall be greater than 1000N. 4.5 Running self-tip
When the ambient temperature is 15% to 35℃ and the relative humidity is not more than 0%, the wiring board shall be Install the terminal on the line pole and fix it in the wiring container. The insulation between the line main and the wiring basin should be not less than 2000M. 4.6 Push and free fall
The wiring cabinet should be able to withstand the free fall and free fall test specified in JB/T9329. The free fall height is 100mm5 Test method
5.t Appearance
Put the connection on a flat plate and check whether it is flat by feel. Others can be checked visually. 5.2 Size
Measure with a microcaliper with an accuracy of 0.02mm according to the provisions of 4.2. 5.3 Water absorption
First, drain the back of the wiring board and place it in a 105%, 110 test box. Weigh the plate to constant weight C for at least twelve times, and the height between the two times of heating should be at least 30mm). Then put it in water and heat it for 4 hours, then put it in the water for 1 hour. Finally, use a wrung towel to absorb the moisture on the surface and holes of the wiring board. , and then weigh its weight as G, and then calculate the water absorption rate with the following formula: xFx100%
or: one water-removal rate,
line - the weight of the wiring pole when it is dry,
center - the weight of the wiring board and after water,
you use a flat instrument with a sensitivity of 0.01
.4 Anti-press ()
5.4.1 Test equipment

JEl/r32391999
According to the starting method, the distance should be calculated according to the method. Before the test, please do not connect the shallow plate and the adhesive lead. The two lower supports will be installed carefully. The center of the connection should be parallel to the support, and the center line of the upper support should be on the same vertical line. The lower side is the force-bearing surface. The negative load is 9/5, and the variable load during the wiring inspection is the range of the terminal block. 5.5 The resistor is placed in the specified environment of 4.5, and then the weekly voltage is 500V, the measurement range is 0%2-0032, and the megohmmeter of not less than ".5" is used for measurement. 5.6 Collision and free auxiliary language connection practice In the case of extreme luxury, the test method of the drop test is carried out by the full and full benefit test 6 Inspection rules 6.1 Strict inspection 6.1.1 The appearance of the line should be inspected according to the B.1.2 size, insulation resistance, water absorption rate of the terminal block CB/282. The results are once the standard column is used, and it is stipulated that: Water absorption level
h) AQL=4.0g
Special: Water absorption test is carried out for no less than 1 time per unit. 6.2 Type inspection
In any of the following situations, type inspection shall be carried out: 6.2.1
Regular inspection of products in normal production:
When the design, process or material of the product is changed; b
When the product that has not been produced is ready for production again. Type inspection is carried out in accordance with the requirements of the rest of the standard. 6.2.21
Type inspection is carried out in accordance with the control sample plan adopted by CB/T7829, and the current identification level is set as level;
RQL= 15:
The whole group is judged as (0.1).
Bags. Transportation and storage
7.1 The board is packed with a box as the inner packaging and a large box as the outer packaging. Both the inner and outer packaging are neatly arranged.The outer packaging is printed with words such as "Preserve crown", "Dehumidifier, Be careful, and Proofread carefully". 7.2 Each pin shall have its own qualification certificate and the manufacturer's installation certificate, product code, date of factory release, inspection number: 7.3 The connector shall be stored indoors or protected from rain and moisture: EE
