The Introduce PCB Assembly SMT Line
In this Topic,we will introduce you about the PCB Assembly SMT line.
SMT Line machine have different machine list,let’s take MOKO TECHNOLOGY LTD SMT lines for example,to introduce you how a SMT line working. This SMT line is ROHS(Pb Free).
1.Auto PCB Loader Machine
The PCB boards, PCB Circuit board will automatic loading to the SMT line by the machine;
2.Auto Soldering Paste machine(Model#:DESEN,CHINA BRAND）
The solder paste are printing in the components position,by use this machine and a set of stencil.
3.SMT Machine-1(Model#:YAMAHA YG200)
SMD Resistors,Capacitors(Package:0805,0603,0402,0201),High Speed SMT assembly.
4.SMT Machine-2/SMT Machine-3( YAMAHA YV100XP *2SETs)
Mailly assembly materials:SMD Resistors,SMD Capacitors, SMD Diode,SMD Transistors)
5.SMT Machine-04( YAMAHA YV88XG)
Mainly materials assembly:IC CHIPS,Special components,SMD USB Card Holder)
6.Relow owen VITRONIC SOLTEC 19 ZONEs
Components place in the Postion and go trough the owen. This processing firstly make the solder paste thaw in Peck Degree,and then the temperature lower.The solder paste solidified,this processing make the components assembly in the PCB boards. And the temperature profile are very important for a success production.
The profile are change according different materials.
7.AOI Test Machine:
AOI machine is a Testing the Components placement by digital camera and Automatic judge by computer.This processing can find out the components not in place ,lack of solder paste,wrong components package. etc.
X-RAY machine is for BGA inspection.The machine can testing the module defective inside in the BGA package.
