5.5 Electro-Static discharge
Normally SIM5216A is mounted on customer host board, although some ESD components have
been added in SIM5216A, to improve ESD, one should put some ESD components on customer
host board. The ESD components should be placed beside the connectors which the human body
might touch, such as SIM card holder, T-flash card holder, audio jacks, switches, keys, etc..
Below is the SIM5216A ESD performance measurement table, the results are got from our EVB
board test.
Table 40: The ESD performance measurement table (Temperature: 25 , Humidity:℃ 45% )
Part Contact discharge Air discharge
VBAT,GND ±4KV ±10KV
UART,USB ±4KV ±8KV
Antenna port ±4KV ±10KV
Other port ±3KV ±8KV
In order to get the best ESD performance, one must deal carefully with ground of SIM5216A
on host board, which is most important. Here are some advices:
1. Bare the copper on the host board.
Figure 36 is SIM5216A PCB decal. There is a big area which is poured with copper.
When one mounts the SIM5216A on host board, the bottom shield of SIM5216A can be
connected to ground well through this copper area. The SIM5216A PCB decal can be got
from our FAE or sales people.
2. Choose 2.0mm height 70-pin socket for host board.
Because the height of 70-pin plug on SIM5216A is 1.5mm, in order to better connecting the
SIM5216A to the ground of the host board, it is suggested to choose 2.0mm height 70-pin socket
for host board. NAS AXK770247G is suitable. 2.5mm will be too high, it will be suspending
above host board. 1.5mm will be too tight.
3. Fill some conductors between the bottom of SIM5216A and host board.
Figure 37 shows the conductor material we use. Other conductor material can be used as well.
4. Solder SIM5216A to ground through 2 out-feet of bottom shield.
