Metal Dome Arrays which may incorporate a large number of domes in a pattern to carter different custom application
Metal Dome Array is mainly sorted by :
A. (Transparent) : Convenient to position alignment
B. (White) :normally used for Light-guide-film, reflection function
C. (Yellow):High-temperature resist material , proceed SMT in the short time
D. (Silver Printing):Grounding anti-static effect
E. (Black) :normally used for light-block
Due to the limited assembly efficiency of single metal dome sheet, In most cases , lots of faactories face to cost increase due to lower efficiency. The the QUESTION is how do we Save money & improve the production efficiency while fitting metal dome array sheet ?
When the order is huge or need greatly improve the productivity , then we , GHD Technology suggested to give priority to formulate PANEL dome sheet design
Compared with the single paste assembly, the advantages of the whole page paste assembly are more obvious
Do not need to add additional procedures, finish the fitting in one step to improve the efficiency
Effectively prevent dust from floating the products & causing defects
It can improve the utilization of PCB board and reduce the cost of client
To make use of the fixture assembly, the work efficiency can be promoted to mini.500 sheet /H.Appro.6~ 10X of single PCS assembly 'S
Metal Dome is mainly used for various key products,such as mobile phones,headphones,MP3 / MP4,all kinds of keyboard,remote control,bank Product keys,medical equipment,industrial instruments and other fields, where there are keys to use products, can use metal dome
