SMD Feeder and Electric Vacuum Pick HAKKO 394 Facilitate Chip Component Mounting

スポンサーリンク

I found an SMD feeder that is very convenient for mounting chip components using the electric vacuum pick HAKKO 394.
The super convenient electric vacuum pick HAKKO 394 is written here ↓
so please read it if you like.

HAKKO 394 for chip parts

It is difficult to pick up chip parts with tweezers.

Chip parts shipped from the manufacturer are packaged in tape and wound on a reel.
At the store, they are sold as they are on the reel or sold in pieces of about 20.

When mounting to a board, it is necessary to take out the parts from the tape.
When mounting a part with tweezers, take the part out of the tape, separate it, and pick it up with tweezers.
Chip parts have both sides.
When the parts are torn from the tape, the parts are front and back.
You have to turn over the parts on the back to make it face up and stick them with tweezers.
This is quite a hard work.

Parts with + – polarity, such as diodes and transistors, are even harder to work with.
The parts on the back side need to be turned over, and even if you face the front side, you have to change the direction of up, down, left and right so that the polarities match.
When the diode is separated, it tends to be on the back side for some reason, and it doesn’t turn easily.

Once the chip components have been separated in this way, it is necessary to orient both the front and back of the components and the top, bottom, left and right directions. This was a very troublesome task.

Chip parts are good manners in tapes

It is a chip parts that is difficult to align when it is separated, but it is facing the front when it is in the tape and the + – polarity is also aligned properly.
If the parts can be picked up in this state, it is not necessary to align the parts.

That’s where the electric vacuum pick HAKKO 394 comes in.

The HAKKO 394 uses an air pump to suck the parts to the tip of the thin nozzle, so the parts in the tape can be sucked out from the top.
The sucked parts can be taken to the mounting location and placed on the board.
The HAKKO 394 allows you to pick directly from within the tape, dramatically improving your efficiency.
This greatly reduces implementation time.

Secure part tape with masking tape

The parts can be taken out from the parts tape, but the parts are very sensitive to the shaking.
When the part tape touches something and moves, the part pops out or turns sideways due to the vibration, and eventually you have to align the direction.
For this reason, it was necessary to carefully secure the parts tape to a desk or the like to prevent shaking.

SMD feeder

Found on Thingiverse

I found “SMD Pick and Place Manual Feeders” on Thingiverse.
It is a tool to fix the tape by putting the tape through it.
I tried printing with a 3D printer right away.
3D printer uses ANYCUBIC i3MEGA.
I recommend it because you can print pretty well at a reasonable price.
This is the SMD feeders.

Insert the tape from this side.

How to use

The tape is passed through the feeder and the film of the tape is passed through the hole in the top.
When the film is pulled, the cover peels off and the orderly array of chip components comes out of the feeder.

Take out the parts using the electric vacuum pick HAKKO 394.

Various parts were mounted.

MAX10 FPGA Substrate

Since the stencil is positioned by the pushpin, the positioning accuracy can be achieved easily.
This article↓ is more detailed about positioning with pushpins.

Perfect.

This board uses a lot of 0402 (JIS 1005) size ceramic capacitors, but thanks to the HAKKO 394 and SMD feeder, it can be mounted smoothly.

Reflow soldering on a hot plate.

MAX5 CPLD substrate

This is a CPLD substrate.

There are many bypass capacitors, but the tape comes out from the feeder with the film peeled, so it can be mounted more and more.

If you pick the LED from the tape, the polarity is always the same, so it is very safe.

It is done by reflow soldering with a hot plate.

DCDC power board for electronic paper

Position the stencil and print the solder paste.

I use a point card for the printing squeegee, but I recommend a card with the same hardness as a credit card.

The solder paste was printed beautifully.

Since it is a DCDC circuit, there are many diodes and capacitors, and there are various values of resistance. It is really easy that you don’t have to align the parts.

The mounting is finished. Even if the orientation of the part is slightly bent, the orientation will be automatically adjusted by the melted solder and the shape of the pattern.

I have been using low temperature lead-free solder since this time. It will melt from about 100 degrees Celsius, and it will be finished if you heat it up to about 150 degrees Celsius. The temperature is lower than that of normal solder, so the heating time can be shortened.

HAKKO 394 and SMDfeeder are convenient

Thanks to the HAKKO 394 and the SMD Feeder, we were able to implement multiple devices in a short time. The SMD Feeder is a convenient tool, so if you have a 3D printer, it is highly recommended.

The optional nozzle A 198 is required to absorb the chip components with the electric vacuum pick HAKKO 394. It may be better to buy several of them because they may touch the solder paste.
