真空钎焊缺陷预防措施 |
真空钎焊缺陷目视解决措施 |
真空钎焊炉内炉渣太多,掉落在产品表面 |
见真空钎焊图片 |
增加烘炉频次 |
真空钎焊炉烘炉频次1次/半月 |
产品表面喷铜,粘焊模 |
见真空钎焊图片
|
焊模表面刷阻焊剂 |
见真空钎焊图片
|
真空钎焊焊模有硬粒,表面隐伤 |
见真空钎焊图片
|
装配前用刷子将焊模清理干净 |
见真空钎焊图片
|
铜未熔化,表面起鼓 |
见真空钎焊图片
|
真空钎焊前仔细检查真空钎焊炉上下门、屏口、碳棒 |
见真空钎焊图片
|
装配时夹紧环靠在芯片组件上,造成粘夹紧环 |
见真空钎焊图片
|
装配时必须保证夹紧环与法兰、芯片组件间有一定的间隙 |
见真空钎焊图片
|
产品组件配合间隙不好,造成白边 |
见真空钎焊图片
|
产品装配时保证间隙≤0.07 |
见真空钎焊图片
|
阻焊剂未干,钎焊后表面发黑 |
见真空钎焊图片
|
阻焊剂必须待干燥后方可装夹 |
见真空钎焊图片
|
真空钎焊焊模不平,造成片闭 |
见真空钎焊图片
|
必须保证真空钎焊焊模垫块平整度(用直尺检查) |
见真空钎焊图片
|
真空钎焊炉内分压压力不足,产品表面喷铜 |
见真空钎焊图片
|
保证真空钎焊炉内分压压力在200~250Pa之间 |

Common defects and preventive measures of vacuum brazing products
Vacuum brazing defect description |
Vacuum brazing defect visual
|
Vacuum brazing defect prevention measures |
vacuum brazing defect visual solution |
Too much slag in vacuum brazing furnace, falling on the surface of the product |
|
Increase frequency of empty furnace heating (without products) |
Vacuum brazing furnace heating frequency 1 / half months |
Product surface spray copper, stick welding mold |
|
Welding surface brush resistance flux |
|
Vacuum brazing die has hard grain, surface hidden injury |
|
Before the assembly with the brush to clean up the welding mould |
|
Copper does not melt, the surface from the drum |
|
Check the vacuum brazing furnace up and down the door, screen mouth, carbon rods carefully before vacuum brazing |
|
The clamping ring is attached to the chip assembly, resulting in a sticky clamping ring
|
|
The Assembly must ensure that there is a gap between the clamping ring and flange and chip components. |
|
Product components with the gap is not good, resulting in white edge |
|
Pressure margin to ensure that the gap ≤ 0.07 |
|
The resistance flux is not dry. The surface is black after brazing |
|
The flux must be dry before clamping |
|
The vacuum brazing is uneven and causes the closure |
|
Must ensure that the vacuum brazing welding pad flatness (with ruler check) |
|
Vacuum brazing furnace partial pressure is insufficient, the product surface spray copper
|
|
To ensure that the vacuum brazing furnace pressure between 200 ~ 250Pa |
