Today we share a client case .They have a desktop pick and place TVM802B machine smt line.
The customer mainly produces control boards for household appliances.This set of equipment can provide him with a lot of convenience for proofing.including stencil printer QH3040→ PNP smt pick and place machine TVM802B→ benchtop reflow oven QRF320
SMT Process Step 1
QH3040 high-precision manual stencil printer The same platform as printer can be selectable , easy to locate both single and double sides of PCB board.High flexibility ensure high printing precision.
The steel stencil can be rotated 30 degrees at most , and the precision can be kept all the way when repeat works, can be comparable with automatic machine.
Using the way of steel stencil movement to adjust the best position, combining with the fine adjustment of X-axis Y-axis to correct, convenient and efficient.
SMT Process Step 2
TVM802B SMT pick and place machine (desktop pnp mounter). The advantages of this model are , optimized driver and software algorithm,2 placement heads，46 slots.
Can handling smallest package size:0402 inch and up to largest size:TQFP100.The external dimensions of TVM802B are 940mm*940mm*320mm. Deluxe edition is mainly composed ofworking head, dual vision system, operation platform, patented feeding rack,, closed-loop motor drive system, internal vacumm pump,etc. Voltage AC220V or AC110V, power 150W.
SMT Process Step 3
- QRF320 SMT Reflow Oven solder welding Mixed Process
- Single-sided mixing process: (Plug-in and surface-mount components are on the A side of the PCB) Incoming material inspection -> Solder paste mixing -> PCB A-side silk-screen solder paste -> Patch -> A-side reflow soldering – > PCB A-side plug-in -> Wave soldering or dip soldering (a small number of plug-ins can be soldered by hand) -> (Cleaning) -> Inspection -> Rework (first post-inserted)
- Double-sided mixing process: (surface mount components on the A side of the PCB, plug-in on the B side of the PCB)
A. Incoming material inspection -> solder paste mixing -> PCB A-side silk screen solder paste -> patch -> reflow soldering -> PCB B-side plug-in -> wave soldering (a small number of plug-ins can be hand soldered) -> (cleaning )-> Inspection -> Rework
B. Incoming material inspection -> PCB A-side silk-screen solder paste -> SMD -> Manual pad on the A side of the PCB pad solder paste -> PCB B-side insert -> Reflow soldering -> (cleaning) – > Inspection -> Rework (surface mount components on the A and B sides of the PCB, plug-in on either or both sides of the PCB) Surface mount components on both sides of the A and B sides of the double-sided PC

What is SMT setup?
Electronics manufacturing using surface-mount technology (SMT) simply means that electronic components are assembled with automated machines that place components on the surface of a board (printed circuit board, PCB).

WHAT IS SMT PROCESS？
There are mainly three steps in SMT assembly line process flow： solder paste printing, components placement and reflow soldering.
- Solder Paste Printing
Its function in SMT line process is to print the solder-free paste on the pads of the PCB to prepare for the soldering of the components. The equipment used is a screen printing machine, located at the forefront of the SMT production line. - Components Placement
Its function is to accurately install the surface mount components on the fixed position of the PCB. The equipment used is a placement machine, located behind the screen printing machine in the SMT production line. - Reflow Soldering
Its function in SMT manufacturing line is to melt the solder paste so that the surface mount components and the PCB board are firmly bonded together. The equipment used is a reflow oven, located behind the placement machine in the fully automatic SMT production line.
WHAT IS SMT pick and place machine？
SMT (Surface Mounted Technology) is a comprehensive system engineering technology, which covers substrates, design, equipment, components, assembly processes, production accessories and management. When it comes to SMT pick and place machines, the automatic SMT production line requires automatic loading and unloading machine, automatic solder paste printing machine, placement machine, reflow soldering machine, AOI inspection equipment, connecting table, etc. For these SMT assembly line equipment, Qihe SMT can offer you machines in prototype SMT line, small SMT production line, mass production SMT line at low SMT line cost. Contact us now if you are interested.
WHAT IS SMT ASSEMBLY LINE？
With the development of technology, future electronic products will be lighter, smaller and thinner. Traditional assembly technology can no longer meet the requirements of high-precision and high-density assembly. A new type of PCB assembly technology-SMT (Surface Mount Technology) has emerged. SMT Assembly is the use of automated machines to assemble electronic components on the surface of the circuit board. Its density, high speed, standardization and other characteristics occupies an absolute advantage in the field of circuit assembly technology. In addition, SMT assembly has a wide range of uses.
