NeoDen YY1 Feeder Configuration Guide: How to Meet Diverse Component Requirements?

Introduction

In the SMT placement process, while the feeder may seem to be responsible only for “feeding” components, it actually has a direct impact on whether components can reliably reach the pick-up position. For PCB prototyping, R&D, and small-batch assembly, a single PCB often contains 0201, 0402, and 0603 resistors and capacitors, ICs, connectors, and other specialized components, all of which are packaged differently.

Therefore, when selecting a pick and place machine, one must not only consider placement speed and accuracy but also ensure that the feeder type, component packaging, pick-up position, nozzle, and recognition method are compatible.

The NeoDen YY1 SMT machine offers multiple feeding solutions for different components, including tape reel, tube, tray, strip, and bulk feeding, with corresponding settings for tape feeders, flexible feeders, and bulk feeders in the software.

Why Are Feeders So Important for SMT Placement?

Whether a pick and place machine can operate stably depends on more than just the placement head.

The complete component placement process is actually:

Feeder → Pick-up → Recognition → Placement

If the feeder’s discharge position is unstable, the nozzle may be unable to pick up components accurately. If the component’s orientation or position is abnormal, vision recognition may also fail. Therefore, for PCBs with multiple component varieties and small batch sizes, feeder flexibility is often more important than simply pursuing a higher CPH.

The NeoDen YY1 supports multiple feeding methods, allowing you to select the appropriate feeder based on the component’s packaging. This flexibility is especially important for R&D teams that need to frequently change PCB and component configurations.

What feeders does the NeoDen YY1 support?

The YY1’s feeding system can be broadly categorized into three types: Tape Feeder, Flexible Feeder, and Bulk Feeder.

Among these, the Tape Feeder is used for common tape-and-reel components. The Flexible Feeder can be used for components in various forms, such as tubes, trays, sticks, and strips. While the Bulk Feeder is designed for bulk components that meet specific criteria. The specific feeding formats listed in the NeoDen YY1 user manual include Tape Reel Feeder, Tube Feeder, Tray Feeder, Bulk Feeder, and Strip Feeder.

This configuration allows the NeoDen YY1 to operate without relying on a single feed format, enabling it to be configured according to the actual BOM.

Tape Reel Feeder: How Are the Most Common SMT Components Fed?

Tape reels are the most common form of component packaging in SMT production, particularly suitable for chip components such as resistors, capacitors, and diodes.

When using the NeoDen YY1 Tape Feeder, you need to adjust the feeding parameters based on the actual tape material and component dimensions. The basic setup process outlined in the manual includes Needle Position, Pick Test, and Pick Position. Since the hole positions and thicknesses of different tapes may vary, the pick-up position must be adjusted according to actual conditions.

This step is particularly important for small components such as 0201 and 0402.

The user manual recommends setting the pick-up position for small components as close as possible to where the component first emerges from the tape, thereby improving the pick-up success rate.

Therefore, if a PCB contains a large number of 0201 or 0402 components, one should not only focus on whether “the machine supports 0201,” but also verify that the Tape Feeder, Nozzle, and Pick-up Position are set correctly.

NeoDen YY1: Supports Tape Reel Feeders and allows adjustment of relevant feeding parameters via software, making it suitable for the automatic placement of common tape-and-reel components.

Stick and Tube Feeders: How to Handle Tube-Packaged Components?

Not all components use tape reels.

Some ICs, connectors, and special components are packaged in tubes or sticks. For these components, the YY1 can use a flexible feeder.

The stick feeder uses vibration to feed components one by one to the pick-up position. When using this feeder, the vibration time and vibration strength must be adjusted according to the specific component. If the vibration parameters are not appropriate, the components may not reach the pick-up position reliably.

This type of feeder is better suited for components that are inherently supplied in tube packaging, rather than for converting all components to tape feeding.

NeoDen YY1: Supports stick/tube-type components via the Flexible Feeder, providing a feeding option for non-tape-reel packaged components.

Tray Feeder: How Are ICs and Special Components Fed?

For some ICs and components with special packaging, trays are often more suitable than tape or stick feeders.

The NeoDen YY1’s Flexible Feeder includes an IC Tray Feeder and a Customized IC Tray Feeder.

When using a Tray Feeder, settings must be configured based on component size, position, and the nozzle. Especially for IC-type components, the feeder is only part of the entire pick-up process; a suitable recognition mode must also be selected.

The YY1 software offers recognition methods such as Camera, Vacuum, Camera + Vacuum, and Big IC Camera, which can be selected based on the component type.

NeoDen YY1: Supports the IC Tray Feeder, which can be used to handle ICs and special components that are not suitable for tape feeding.

Strip Feeder: Capable of Handling Short Strips and Small Quantities of Components

For PCB prototyping and small-batch production, engineers often encounter a situation where certain components are available in limited quantities—only a short strip of tape rather than a full reel.

In such cases, a strip feeder offers a more flexible solution.

The NeoDen YY1’s strip feeder is a flexible feeder that allows for the adjustment of pitch, rows, and pick height. The user manual specifically notes that if the pick height is set too low, it may cause vibration that affects subsequent components. Therefore, it must be adjusted based on the actual component positions.

For R&D and pilot production scenarios, this flexible feeding method reduces the need to prepare a full reel just for a small number of components.

NeoDen YY1: Supports the Strip Feeder, suitable for special feeding requirements such as short strips and strip-shaped components.

Bulk Feeder: Can bulk components be used directly?

The YY1 also offers a Bulk Feeder for eligible bulk components.

Its operation differs from that of a Tape Feeder. The system uses a down-looking camera to locate components in the feeding area before picking them up. To ensure accurate recognition, bulk components must not be heavily overlapped or arranged too densely, and the pick position area must meet the corresponding visual recognition requirements.

It is important to note that the manual explicitly states that the Bulk Feeder has certain usage restrictions—for example, it is not suitable for IC-type components—and recommends checking the position and orientation of components after placement.

Therefore, a more accurate statement is not “YY1 can handle all bulk components,” but rather:

YY1 supports bulk feeding for suitable loose components when the feeding and recognition conditions are properly controlled.

NeoDen YY1: Provides a bulk feeder, offering an alternative automated feeding method for eligible bulk components.

In addition to the feeder, the nozzle also determines pick-up performance.

After components exit the feeder, they must be picked up by the nozzle. Therefore, the feeder and nozzle must be considered as a combined system.

The NeoDen YY1 placement machine supports a variety of nozzles. For example:

For a PCB that contains chips, SOPs, and other ICs, you need to select the appropriate nozzle based on the component size and shape, and then combine it with the corresponding recognition mode.

Therefore, a reasonable configuration should consider:

Component → Feeder → Pick-up Position → Nozzle → Recognition Mode

rather than selecting the feeder in isolation.

How should the YY1 Feeder be configured based on the PCB’s BOM?

When configuring the system, follow the process below.

Step 1: Organize Component Packaging

First, list the package type, dimensions, and packaging for each component based on the BOM.

For example:

Step 2: Check Small Components

If the PCB contains 0201 or 0402 components, test the pick-up position in advance and confirm the corresponding nozzle.

Step 3: Determine the Recognition Method

Select a recognition mode—such as Camera, Vacuum, Camera + Vacuum, or Big IC Camera—based on the component type.

Step 4: Perform a Pick Test Before Production

YY1 offers a Pick Test function that simulates feeder pickup without actually picking up components.

During the first production run, you can also use Step mode to place a small number of components first. After verifying the feeder, nozzle, and placement parameters, proceed to continuous production.

How should feeders be configured for different production scenarios?

1. PCB Prototyping

Component types change rapidly during the R&D phase, so flexibility should be a top priority.

Recommended Approach: Tape Feeder + Flexible Feeder + Strip Feeder.

2. Small-Batch SMT Production

If the product has entered the repeat production phase, commonly used resistors and capacitors can be permanently configured on the Tape Feeder, with Stick, Tray, or other feeders added as needed for special components.

3. R&D Laboratory

R&D laboratories typically handle a small number of components but with complex packaging formats. In this scenario, the value of a Flexible Feeder becomes even more apparent, as it reduces the need to prepare entirely different equipment for different components.

FAQ About NeoDen YY1 Feeder Configuration

Q1. Why can’t the feeder pick up components even though it’s already installed?

A. First, check the Needle Position, Pick-up Position, Nozzle, and Recognition Settings. For 0201 and 0402 components, also pay close attention to whether the components can reach the pick-up position stably.

Q2. Why can’t the Bulk Feeder recognize components?

A. Check whether the components are overlapping or too densely packed, and verify that the background color and Camera Threshold are appropriate.

Q3. Why are components downstream of the Strip Feeder also affected?

A. Check the Pick Height. Setting it too low may cause vibration and affect subsequent components.

Q4. Can the NeoDen YY1 use different types of feeders simultaneously?

A. Yes. The YY1’s feeding system is designed to support multiple feeder configurations for different component packaging; the actual combination should be determined based on the PCB BOM and production requirements.

Conclusion

A single PCB may contain various component packaging types, such as tape, tube, tray, strip, and bulk. A stable production process can only be established by selecting the appropriate feeding method based on the component type and correctly configuring the pick-up position, nozzle, and recognition mode.

If you are planning the feeder configuration for the NeoDen YY1, you should configure it based on your BOM, component packaging types, and PCB types, rather than simply selecting equipment based on the number of feeders.
