1. Lazima iwe na utupu

2. Idadi ya PCB bodi per stack is limited according to the size is too small

3. Vipimo vya kubana kwa kila rundo la mipako ya filamu ya PE na kanuni za upana wa ukingo

4. Mahitaji maalum ya filamu ya PE na Karatasi ya Viputo vya Hewa

5. Vipimo vya uzito wa carton na wengine

6. Je, kuna kanuni maalum za kuweka akiba kabla ya kuweka ubao ndani ya katoni?

7. Vipimo vya kiwango cha upinzani baada ya kufungwa

8. Uzito wa kila sanduku ni mdogo

Kwa sasa, ufungaji wa ngozi ya utupu wa ndani ni sawa, tofauti kuu ni eneo la kazi la ufanisi tu na kiwango cha automatisering.

tahadhari:

a. Taarifa ambazo lazima ziandikwe nje ya kisanduku, kama vile “kichwa cha ngano simulizi”, nambari ya nyenzo (P/N), toleo, muda, kiasi, taarifa muhimu, n.k. Na maneno Imetengenezwa Taiwan (ikiwa imehamishwa).

b. Ambatanisha vyeti husika vya ubora, kama vile vipande, ripoti za weldability, rekodi za majaribio na baadhi ya ripoti za majaribio zinazohitajika na wateja mbalimbali, na uziweke kwa njia iliyobainishwa na mteja. Ufungaji sio swali la chuo kikuu. Kuifanya kwa moyo wako itaokoa shida nyingi ambazo hazipaswi kutokea.

The circuit board is no better than other products, and it cannot be in contact with air and water. First of all, the PCB board cannot be damaged by vacuum. A layer of bubble film must be placed on the side of the box when packing. The bubble film has better water absorption, which plays a very good role in preventing moisture. Of course, moisture-proof beads are also indispensable. Then sort them and place them on labels. After sealing, the box must be stored in a dry and ventilated place with partition walls and off the ground, and avoid sunlight. The temperature of the warehouse is best controlled at 23±3℃, 55±10%RH. Under such conditions, PCB boards with surface treatments such as immersion gold, electro-gold, spray tin, and silver plating can generally be stored for 6 months. 3 PCB boards with surface treatment such as tin sink and OSP can generally be stored.
