The process and function of smt splice tape
Smt splice tape
1)it is to improve the production efficiency greatly, if you stop receiving, every time spent about 2 minutes, this is the fastest, a machine running a minute is $1.3, which is a waste of 2*8= $2.4; if the splice tape saves the time spent two receiving only $0.06.
2) can greatly avoid material waste: avoid material is too short, and can not use the machine and discard, can use all the remaining material.
3) it is to reduce the mechanical loss of machine, feeder, etc., reduce the machine frequently stop and open, avoid frequent pulling and other movements of the feeder, and prolong its service life.
4) it is possible to avoid some man-made accidents due to the switch cover.
Remarks: the color of the receiving belt is: deep yellow (S), dark blue (N), dumb black - anti-static (M-ESD), bright black - anti-static (G-ESD), transparent green - anti-static (L-ESD).
Product advantage editor
1. no auxiliary tools required
2. improve process efficiency
3. easy to operate and save labor.
4. reliability, high accuracy
5. make full use of the remaining materials
After understanding the tape, look at the role of the entire SMT process:
(printing or dispensing), mount (curing) - reflow soldering, cleaning, repair ---- the detection screen: its role is to pad solder paste or adhesive printed to the circuit board, preparing for welding components. The equipment used is silk
Printing machine (screen printing machine), located at the front of the SMT production line.
Dispensing: it is to glue drops to the fixed position of the circuit board, and its main function is to fix the components to the circuit board. The equipment used is the dispenser, located at the front of the SMT receiving strip production line or behind the inspection equipment.
Mount: the function is to install the surface assembly components accurately to the fixed position of the circuit board. The equipment used as mounter, located in the Ssmt splice tape production line, screen printing machine behind.
Curing: the function is to melt the chip adhesive so that the surface assembly elements and the circuit board are firmly bonded together.
The equipment used is a curing furnace, which is located behind the placement machine in the production line of smt splice tape.
Reflow soldering: the function is to melt solder paste, so that the surface assembly components and circuit boards firmly bonded together.
The equipment used is reflow oven, which is located behind the placement machine in the production line of smt splice tape.
Cleaning: the function is to remove the harmful welding residue, such as soldering flux, on the assembled circuit board.
The equipment used for cleaning machine, location can not be fixed, you can online or online.
The equipment used for the reflow furnace, smt is located in the production line with the placement machine behind. Cleaning: the role of the circuit board assembly is harmful to the human body above the welding residues such as flux removed. The equipment used for the cleaning machine, the location can not be fixed, can be online, or not online. Detection: The role of the assembled circuit board for welding quality and assembly quality testing.
The equipment used is a magnifying glass, microscope, on-line tester (ICT), flying probe tester, automatic optical detection (AOI), X-RAY detection system, functional tester. Location according to the detection needs, can be configured in the production line where appropriate. Rework: Its role is to detect the failure of the circuit board rework. The tools used for the iron, rework stations. smt splice tape,Configured anywhere in the production line.
