Placement equipment is the most important part of SMT line configuration. Almost 50% of the total investment cost is required to purchase pick and place machines with feeders to set up surface-mount production lines.

Selection Criteria for Best SMT Pick and Place Machine

A pick and place machine is a crucial part of a production line in the manufacturing industry. Manufacturing companies, such as small businesses use a pick and place machine to assemble a wide variety of products. A pick and place machine is a machine that automatically picks, places, and then seals items into packages. These machines are used in various places, from offices to factories.

The way a pick and place machine is selected is contingent on a number of factors. Selection of Pick and Place Machine depends on your PCBA types and the number of parts placed. Production volume needs for current and future enchantments and accuracy with repeatability.

If you’re wondering how to choose the best SMT to pick and place machine for your production line, you might want to consider the following questions: -How many concurrent operations does the machine support? -What is the maximum part weight? -Does the machine have an in-feed table? -How many tools does the machine support? -What is the maximum part size? -What is the maximum case packing size? -What is the maximum component

If you plan to set up a new pick and place machine for the PCB assembly line, you should make a detailed set of questionnaires of planned production requirements in advance.

This will help narrow down your list and help to make a purchase decision for the best suitable equipment selection to meet your specific needs.

Component Placement Speed

Knowing how fast your component placements are is essential since they directly affect your production volume. Components per hour placement (CPH) is the unit of measurement for the machine’s placement speed. Chip shooters, designed for speed, can place parts at rates as high as 100,000 CPH (components per hour).

The component placement rate will vary depending on the board size, component types, and feeders. The placement head will travel more distance if the board size is large and the type of components is high, which will decrease the placement rate. IPC 9830 is the standard that pick and place machine manufacturers use to rate the speed of their machines. Nevertheless, manufacturers’ quoted speeds are lowered by 30 to 40% and should be considered.

  • Quoted Rated Speed always lowers the actual speed, so consider only 30 to 40%.
  • It is necessary to analyze the production volume proposed before selecting a machine.

Therefore, before selecting a pick and place machine for PCB assembly, it is important to consider the production volume to meet your current and future demands to address specific needs.

Component types and their sizes

In addition to your production needs, pick and place machines for PCB assembly depend on the type and size of components you are planning to place.

  • Precision can be achieved with minimum and maximum component dimensions.
  • Tubes and components may also be found in some parts, so it is essential to consider these details when placing a machine purchase order.
  • Machine vision systems can handle fine-pitch and small components during placement.

Machine specifications stipulate the maximum and minimum dimensions and weights of components that each machine can handle. For example, equipment required for placing 0805, 1206, etc., components is different than that for placing 0402, 0603, BGA, CSP, and other oddly shaped components.

Feeder Slots and Maximum feeder Capacity

A thorough study of product assembly in-house should consider how many types and components are needed and which feeder slots machines are required for specific needs. We need to consider that A pick and place machine for PCB assembly manufacturers benchmarks the feeder slot capacity based on tape feeders with a diameter of 8 mm.

There may also be tubes and other components in some parts, so it is essential to consider these details when ordering a machine. Realistically, tape and reel components and sticks and tubes take up multiple 8 mm feeder slots. So, Input slots are directly affected by the comports included in bulk and waffle packs.

Accuracy and Repeatability

According to experts, the pick and place machine smd that you are looking for has an accuracy of +/-.001″ with a fine pitch lead of 12 mil repeatability. A less expensive machine, however, would not produce such accurate results.

  • Pick and place machine for PCB assembly must have an Accuracy of 0.0001” with a fine pitch lead of 12 mils repeatedly.
  • Lower Budget machines have poor accuracy.

Solder Paste and Adhesive Dispensing capability

Many smd pick and place machines offer options that can place components and dispense solder paste or glue with standard XY tables. The purchase of a dispensing placement machine can be recommended for smaller-volume production, prototypes, or PCB assembly. The customer does not want to invest in dedicated stencils or foils.

It would be better to have a solder paste and adhesive dispenser for low volume and prototyping. The pick and place machine selection decision should also consider the production volume because a single head needs to perform both operations, which slows down throughput.

But the pick and place machine smd selection decision must be based on the production volume requirements as the same head needs to use both operations that slow down the throughput.

Machine software programming

Pick and Place Machines have varying software interfaces available on the market. Although some are user-friendly and easy to operate, others require manual data entry and can be challenging to edit and optimize.

A user-friendly and easy-to-program device is essential and Lowers the setup optimization time. Therefore, choosing and placing a PCB assembly machine that is easy to program and edit is a crucial selection criterion to reduce setup times and improve performance.

So it is a crucial selection criterion to pick and place a machine for PCB assembly. Equipment must be easy to program and edit to set up time reduction and improve performance.

Vendor Support and Training

Pick and place machines for PCB assembly selection is driven by technical features and vendor support and training. You will need support to troubleshoot machines quickly if you have a breakdown to meet supply chain obligations.

To get the best information about machines, vendors, and their product support, it would be better to talk to several customers about the equipment you’re searching for.

To develop skills for operating machines, proper training is required, as a skilled workforce is crucial to the success of any organization. Therefore, keep in mind that the machine supplier can provide onsite training or factoring before delivering and installing the equipment.

  • Pick and place machine for PCB assembly must have an Accuracy of 0.0001” with a fine pitch lead of 12 mils repeatedly.
  • Availability of spare parts shipment on time.
