进入七月以来,国内多地接连高温
仅今年第27周,空调线上市场销售额就同比激增63%,线下更是暴增120%*
这种时候,有个成本不足整机3%的元件,却会成为出货的致命瓶颈Since July, many parts of China have experienced continuous high
temperatures.
In just the 27th week of this year, online air conditioner sales surged by 63%
year-on-year, and offline sales increased by a staggering 120%*
During such times, a component that
costs less than 3% of the total machine becomes a fatal bottleneck in shipment

IPM的结构和要害The Structure and
Critical Points of IPM
IPM为6合1封装结构,分为IGBT芯片-DBC-基板-焊料-引脚-外壳
它整合了整个压缩机需要的功率开关器件+驱动电路+保护电路
既要承受千瓦级功率的摧残,又要实现微秒级精准控制,面对的挑战可想而知IPM has a 6-in-1 package structure, consisting of IGBT
chip-DBC-substrate-solder-pins-housing
It integrates all power switching devices, drive circuits,
and protection circuits required by the compressor
It must withstand the destruction of
kilowatt-level power while achieving microsecond-level precise control, facing challenges that can be
imagined

WireBonding-引线键合质量检测WireBonding - Lead Bonding Quality Inspection
问题背景:Problem
Background:
IPM模块内部通过金线/铜线连接芯片与引脚,若键合点存在偏移、断裂、弧度不足,会导致空调压缩机驱动失效。The IPM module connects chips to pins through gold/copper wires internally. If
the bonding points have offset, breakage, or insufficient curvature, it will lead to air conditioner
compressor drive failure.
解决方案:Solution:
- 多角度穿透成像:通过X射线多视角透视IPM模块,清晰呈现引线键合点的三维空间位置
-
AI缺陷捕捉:AI算法自动标记键合线脱焊、弧形塌陷、交叉短路等异常- Multi-angle
penetration imaging: Through X-ray multi-angle perspective of the IPM module, clearly presenting the
three-dimensional spatial position of lead bonding points
- AI defect capture: AI algorithms
automatically mark abnormalities such as bond wire desoldering, arc collapse, and cross short
circuits

Die Bonding-芯片贴装偏移检测Die
Bonding - Chip Mounting Offset Detection
问题背景:Problem
Background:
功率芯片(如IGBT)与陶瓷基板间的银浆/焊料层若存在空洞或偏移,会引发散热不均,导致IPM模块过热烧毁。If there are voids or offsets in the silver paste/solder layer between power
chips (such as IGBT) and ceramic substrates, it will cause uneven heat dissipation, leading to
overheating and burnout of the IPM module.
解决方案:Solution:
- 分层成像技术:针对IPM的6层结构,逐层分析贴装界面。
-
数据互联:依客户实际需求接入MES、ERP、WMS等系统,实时上传检测数据。- Layered
imaging technology: Targeting the 6-layer structure of IPM, analyzing mounting interfaces layer by
layer.
- Data interconnection: Connecting to MES, ERP, WMS and other systems according to
customers' actual needs, uploading detection data in real-time.
