What Are SMT Machines? What’s the Function?
Máquinas SMT, also known as Surface Mount Technology machines, refer to a broader category of machines in the Tecnologia de montagem em superfície process including equipment for placing components, applying solder paste, Soldadura por refluxo, and inspection systems. Na verdade, these machines allow us to position surface mount components, como resistores, capacitores, integrated circuits and LEDs, rapidly and accurately at certain locations on a PCB. SMT machines can place as little as 0.4 x 0.2mm, and they can place hundreds or even thousands of parts per hour. They aid in the increase in the manufacturing production speed and accuracy and are used widely around the world.
Different Types of Surface Mount Assembly Machines
De acordo com a sequência do Montagem SMT PCB processo, we will list the equipment used one by one:
- Solder Paste Printing Machine
In SMT process, this machine exactly apply the solder paste on the PCB pads. É assim que funciona: In using a stencil and squeegee system to distribute the paste evenly, they are able to make sure the components will be mounted correctly in subsequent stages.
- Inspeção de pasta de solda (SPI) Máquina
After applying paste, this crucial machine then uses advanced 3D imaging to inspect the solder paste. It grades volume, alignment and height while identifying any defects that could cause soldering problems.
- Máquina Pick-and-Place:
This kind of machines are available in three types:
- Manual: Hand operated, suitable for small volume production or rework.
- Semi-Automatic: Combines manual and automatic features, providing computerized visualization to guide operators in accurate component placement.
- Automatic: The most advanced type, offering high speed, precisão, e eficiência. It significantly reduces labor costs and human error.
- Forno de cura de montagem SMT
After component placement, this oven then cures the solder paste and secures components to the PCB.
- Máquina de solda por refluxo
This critical equipment is used to preheat components and melt the solder paste which in turn form permanent connection between the SMDs to the PCB. The design is meant to enable solid joints without damaging sensitive parts.
- Equipamento de limpeza com solvente
This machine removes any residual flux and excess solder from PCB to give a clean surface for best performance.
- Equipamento de reparo e inspeção
The last stage which comes in at a sophisticated machinery that checks assembled PCB for any defect. além do que, além do mais, it assists in fixing these issues to ensure the quality.

How to Choose the Best Surface Mount Machines?
Escolher uma máquina SMT adequada para sua linha de montagem não é uma tarefa fácil, existem vários fatores que você deve considerar antes de tomar a decisão:
- Velocidade de colocação do componente
The focus of the initial research on the purchase of SMT placement machine is on the placement speed. There exist different placement machines, at different placement speed and it is essential to select one that fits within your production needs and your budget. They can be checked against the IPC 9850 padrão, which states the desired speed of their pick and place machines.
- Precisão do posicionamento
Another important aspect is placement accuracy. With more accurate machines, yields are higher and they can perform better. To get the best accuracy you need an optimal SMT machine with an accuracy of 0.0001″ and a fine pitch lead of 12mil.
- Repetibilidade da máquina
Claro, picking an SMT machine is not only about how accurate it will be, but also if it will consistently produce the same results. Repeatability is another factor you should consider, especially with machines that run on programmed software solutions.
- Tamanho das peças
Outro fator importante a considerar é o tamanho da peça. Por exemplo, uma máquina pick-and-place deve ser capaz de manusear peças de tamanhos 0402, 0201, e 01005. If your other requirements for your machine are being met, but the machine does not support these sizes, you can buy a nozzle (or a feeder) which will make it possible to produce circuit boards of these sizes.
