11.1 注意事項(xiàng) Matters needing attention
X光掃描 X-Ray Screen
Mic 不能進(jìn)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(jìn)行檢測(cè)，檢測(cè)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(shí)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(fēng)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(shí)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(guò)程后不要清洗板子是很重要的。這會(huì)損壞麥克風(fēng)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(fēng)的口洞上拉一個(gè)真空。這會(huì)損壞麥克風(fēng)的。
It is very important not to pull a vacuum over the port hole of the MIC. This could damage the MIC.
