The Ultimate Guide to SMT Machines: What They Are & Hoe te kiezen

What Are SMT Machines? What’s the Function?

SMT machines, also known as Surface Mount Technology machines, refer to a broader category of machines in the Technologie voor opbouwmontage process including equipment for placing components, applying solder paste, reflow-solderen, and inspection systems. In feite, these machines allow us to position surface mount components, like resistors, condensatoren, 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

Volgens de volgorde van de SMT PCB-assemblage werkwijze, 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. Dit is hoe het werkt: 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.

• Inspectie van soldeerpasta (SPI) Machine

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.

• Pick-and-place-machine:

This kind of machines are available in three types:

1. Handleiding: Hand operated, suitable for small volume production or rework.
2. Semi-Automatic: Combines manual and automatic features, providing computerized visualization to guide operators in accurate component placement.
3. Automatic: The most advanced type, offering high speed, nauwkeurigheid, en efficiëntie. It significantly reduces labor costs and human error.

• SMT montage uithardingsoven

After component placement, this oven then cures the solder paste and secures components to the PCB.

• Reflow-soldeermachine

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.

• Oplosmiddel reinigingsapparatuur

This machine removes any residual flux and excess solder from PCB to give a clean surface for best performance.

• Reparatie- en inspectieapparatuur

The last stage which comes in at a sophisticated machinery that checks assembled PCB for any defect. Daarnaast, it assists in fixing these issues to ensure the quality.

How to Choose the Best Surface Mount Machines?

Het kiezen van een geschikte SMT-machine voor uw assemblagelijn is geen gemakkelijke taak, er zijn verschillende factoren waarmee u rekening moet houden voordat u de beslissing neemt:

• Component plaatsingssnelheid

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 standaard-, which states the desired speed of their pick and place machines.

• Plaatsingsnauwkeurigheid

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.

• Herhaalbaarheid van machines

Natuurlijk, 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.

• Onderdelen Grootte

Een andere belangrijke factor om te overwegen is de grootte van het onderdeel. Bijvoorbeeld, een pick-and-place machine moet onderdelen van formaat kunnen verwerken 0402, 0201, en 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.
