In the marketplace, there are a lot of different placement equipment options available. To meet customer expectations and the latest technology requirements machine manufacturers are constantly upgrading their features.
So it is very important to get the answer to How To Choose the Best Pick and Place Machine for PCB Assembly Machine before ordering.
Placement equipment is the most important part of SMT line configuration. Almost 50% of the cost of total investment 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
Evolution and selection of a pick and place machine smd is a very complex process that needs to do a lot of investigation and homework to meet your production requirements.
Selection of Pick and Place Machine depends on your PCBA types and number of parts to be placed, production volume needs for current and future enchantments, and accuracy with repeatability.
If you are planning to set up a new pick and place machine for the PCB assembly production line it is recommended to make a detailed set of questionnaires of planned production requirements in advance.
This will help to narrow down your list and help to make a purchase decision for the best fitted suitable equipment selection to meet your specific needs.
Component Placement Speed
It is important to know how fast your component placements are 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, which are designed for speed, can place component parts at rates as high as 100,000 CPH (components per hour).
Depending on the board size, component types, and feeders used, the component placement rate will vary. 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, in reality, manufacturers’ quoted speeds are lowered by 30 to 40% and should be taken into account.
Therefore, before selecting a pick and place machine for PCB assembly, it is important to consider the production volume to be able to meet your current needs, as well as future demands to address specific needs.
Component types and their sizes
In addition to your production needs, the choice of pick and place machines for PCB assembly is also dependent upon the type and size of components you are planning to place.
Machine specifications stipulate the maximum and minimum dimensions and weights of components that can be handled by each machine. 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 a number of components are needed, and which feeder slots machines are required for specific needs. Need to consider that A pick and place machine for PCB assembly manufacturers benchmarks the feeder slot capacity based on types of tape feeders with a diameter of 8 mm.
There may also be tubes and other components in some parts, so it is important to consider these details when ordering a machine. Realistically, tape and reel components, as well as 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.
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 in which the customer does not want to invest in dedicated stencils or foils.
For low volume and prototyping, it would be better to have a solder paste and adhesive dispenser. The pick and place machine selection decision should also take into account the volume of production 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 of them are user-friendly and easy to operate, others require manual data entry and can be difficult 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 an important selection criterion to reduce setup times and improve performance.
So it is an important selection criterion to pick and place a machine for PCB assembly that equipment must be easy to program and edit to setup time reduction and improving performance.
Vendor Support and Training
Pick and place machines for PCB assembly selection is not only driven by technical features but also by vendor support and training. You will need support to troubleshoot machines quickly in case you have a breakdown so you can meet supply chain obligations.
To get the best information about machines, vendors, and their product support it would be better to talk to several of your customers about the equipment you’re searching for.
To develop skills for operating machines, proper training is required, as skilled manpower 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.
Conclusion – Wrapping it up
As an SMT line manufacturer, the above article will serve as a guide for choosing the best equipment for your assembly line. Adding a pick-and-place machine to your PCB production line must be considered as part of your future plans
We’re going to give you some honest advice you’ll thank us for later – a used pick and place machine from a reputable market place for used equipment can do a lot more than you might imagine. The types of factors you need to consider in making sure that you purchase the right pick and place machine may prevent you from receiving the best solution for your needs when you spend tons on a new SMT machine.
