1. 目的

此可靠性测试检验规范的目的是尽可能地挖掘由设计，制造或元器件所引发的电子部分潜在性问题，在正式生产之前寻找改善方法并解决上述问题点，为正式生产在产品质量上做必要的保证。

2. 范围

本规范仅适用于XXX公司手机电气特性测试。

3. 定义

UUT (Unit Under Test)被测试手机

EVT (Engineering Verification/validate Test)       工程验证测试

DVT (Design Verification Test)       设计验证测试

PVT (Product Verification Test)生产验证测试

4. 引用文件

《成品检验规范》XXX公司作业指导书

5. 测试样品需求数

总的样品需求为12台。

6. 测试项目及要求

6.1 初始化测试

6.1.1 外观功能检验

在实验前都首先需要进行初始化测试，以保证UUT没有存在功能上的不良。如果碰到外观上的不良则需要先记录然后开始试验。在实验后也要进行初始化测试，检验经过实验是否造成不良。具体测试请参见《成品检验规范》。

6.1.2 其他检验

6.1.2.1 内部结构检验

Purpose

This is to check if there isn’t any problem in the phone structure.

Description

Guideline for internal inspection of DUT after the test.

Procedure

Remove the cabinet, caps and shield and check following items:

1. Operability
2. Torque for screw
3. Wiring and its soldering
4. Soldering of parts and clearance with neighbor parts
5. Smoothness of moving-parts
6. Application of adhesive
7. Invasion of foreign substances

Pass/Fail Criteria:

Apart from the general pass/fail criteria the following results constitute a failure:

• Any damage including cabinet, shield, caps, PWB and battery
• Any wrong assembly
• Any change of performance

6.1.2.2 通话质量检验

Purpose

This test is to confirm the subjective sound quality of the phone.

Description

Check subjective quality of call and reception from Landline to mobile and from mobile to mobile.

Procedure

Temperature:23±5C

Humidity:            35...70% rel. humidity

According to the below list, check transmission/reception voice quality between L-M/M-M (L=Land line phone, M=Mobile phone). The test is a subjective test depending on the test-person and network conditions. If telephone line is not available the cellular tester can replace it.

Pass/fail criteria

Any deviation according to the table below must be reported for further investigation.

6.1.2.3 产品使用说明书检验

Purpose

This check is performed to check the consistency between instruction manual and product.

Description

Check the content of the instruction manual except the functional description.

Procedure

Check items are:

1. Trouble shooting list
2. Technical data
3. Safety recommendations
4. Disposal and recycling recommendations
5. Charging recommendations
6. Appearance of the product in accordance to the manual
7. Declaration of conformity (if applicable)
8. FCC statement (if applicable)

Pass/fail criteria

Apart from the general pass/fail criteria the following results constitute a failure:

• Any inconsistency in the instruction manual

6.1.2.4 Field test

Purpose

The purpose of this test is to confirm that there is no influence of electrical car equipment to the call quality.

Description

Check if disturbances caused by electrical car equipment have an influence to the call quality.

Procedure

Temperature:23±5C

Humidity:35…70% Rel. humidity

Status of DUT:                  power ON

Test set-up

Perform the test handheld (co-driver!) and in a cradle (external antenna).

Procedure

1. Set up a call to landline.
2. Start the engine.
3. Turn all electrical equipment on: lights, indicators, wipers, car radio, blower/air condition, heating of back-window.
4. Turn all off (except ignition).
5. Repeat the same procedure while driving at 50km/h and 100km/h.

Pass/fail criteria

The following results constitute a failure:

• Disturbances, functional problems due to car use.

6.2 电子性能测试

6.2.1 耗电流测试

主要检验UUT在各种模式下的电流使用情况，并根据实际电池的容量在理论上计算UUT各种工作模式的使用时间。

6.2.1.1 基本测试

测试样品：2台

测试仪器：1.HP8960 & HP66321；

2.Dummy Battery；

3.测试SIM卡和实际网络SIM卡(移动卡和联通卡)；

4.安装GPIB卡PC；

测试环境：  1.常温 25 +/- 3ºC；常湿 60%RH +/-5；

2.相对屏蔽的测试环境(可以使用Shielding Box)；

测试要求：1.在模拟网络和实际网络两种状态下，都需要对当电池电压为高(4.2V)，中(3.7V)，低(3.2V)三种情况下进行测试，测试项目主要是分别在关机，待机和通话模式下的耗电流检测。

2.在模拟网络状态下，按照GSM band和DCS band分别设置如下测试参数。

3.在实际网络下测试时，应该保持Cell Power在-65dB ~ -85dB之间。
