11.1 注意事項 Matters needing attention
X光掃描 X-Ray Screen
Mic 不能進行X光掃描，如果必須要用X光做BGA掃描，最大劑量需按照下面圖表，Mic 的靈敏度在掃描之前和
之后都需要進行檢測，檢測值需記錄作為參考。
The MIC should not be subjected to x-ray screening if it is absolutely necessary bo do BGA screening
By x-ray.the maximum dose applied to the MIC untshould be restricted per Table 11-1 The sensitivity of
The MIC shall be measured before and afire.The values should be recorded for reference.
Table 11-1 X-Ray Parameter
Parameter | Level Value | Unit |
X-Ray Current 電流 | ﹤0.080 | mA |
Distance 距離 | ﹥0.30 | m |
Duration 時間 | ﹤30 | s |
11.2電離空氣凈化 Ionized air cleaning
不要直接把電離氣槍帶到麥克風的聲音出口。
Do not bring the ionized air gun to microphone’s sound outlet directly.
建議的條件: 距離﹥8cm;時間﹤5 sec
Recommended condition (Distance＞8cm; Time＜5 sec.)
11.3 木板清洗限制 Board wash restrictions
在回火過程后不要清洗板子是很重要的。這會損壞麥克風的。
It is very important not to wash the board after the reflow process. This could damage the MIC.
11.4 真空限制 Vacuum restrictions
非常重要的是不要在麥克風的口洞上拉一個真空。這會損壞麥克風的。
It is very important not to pull a vacuum over the port hole of the MIC. This could damage the MIC.
