How to operate PCB drilled too pin

1. Operating procedures for PCB laser drilling machine:

1. Preparation before starting.

Carefully check whether the parts of the drilling machine are complete.

Whether the screws are loose or not.

Whether the lubricating oil meets the required position.

Control whether the buttons are flexible and reliable.

Whether the drill pipe and drill bit are damaged.

Whether the branch frame is broken.

Whether the spraying facilities are in place.

2. Turn on normally.

The drill machine idles for 1 to 2 minutes, listening carefully for abnormal noises and noises.

Slowly punch the hole at low speed.

There is no abnormality in the low-speed gear and there is no gangue in the coal seam can be properly adjusted to the drilling speed, if the coal seam has been containing gangue and the hardness of the gangue is larger, it can only be drilled with a low-speed gear, otherwise a fine of 500 yuan will be found.

3. Shutdown. After a borehole is normally drilled, the drill pipe, drill bit, and drilling frame should be dismantled in time.

The dismantled drill pipes, drill bits, and hole support frames should be placed neatly, hygienically clean, and do not affect the safety of pedestrians.

After the shutdown, the floating coal of the drilling body should be cleaned up in time, and the oil stain of the drilling body should be cleaned and placed neatly.

The explosion-proof switches, cables, and control buttons of the drilling machine are sorted out, and placed in a place that does not hinder the safety of pedestrians and placed neatly.

2. Drilling machine refers to the machinery and equipment that uses tools that are harder and sharper than the target to leave cylindrical holes or holes on the target by means of rotary cutting or rotary extrusion. It is also called a drilling rig, a hole punching machine, an eye-punching machine, a through-hole machine, etc. By drilling precision components to achieve the desired effect, the drilling machine has a semi-automatic drilling machine and a fully automatic drilling machine, with the increase of human resource costs; Most companies are considering fully automatic drilling machines as a development direction.

With the development of the times, the improvement of the drilling technology of the automatic drilling machine, the use of automatic drilling machine to drill various hardware molds, strap drilling, strap drilling, jewelry has obvious advantages.

This question will be difficult to explain for a while, you should still operate according to the manual!

Before operation, the equipment (main air pressure, large diameter pressure angle, small diameter pressure angle, dust collection pressure) should be checked first. Pay attention to the type of backing plate (the lower limit of the environmental protection backing plate, the phenolic backing plate, the upper plate clamp pin the plate, and draw the anti-jam hole and write the shaft number. Paste aluminum sheet (ordinary aluminum sheet, lae aluminum sheet), knock pin.

According to the part number, the program expands and contracts, the compensation value calls up the drilling program, the first batch of boards is the first piece, the batch number is measured, the work order is determined, the six axes are checked to see if they are open, the needle is broken, and the function is performed. The diameter of the needle is changed to distinguish the drill needle from the groove cutter, the drill needle drills a round hole, and the groove cutter drills the groove empty. The color of the collar is not the same for drill needles and grooved cutters of the same diameter.

The handle identification of the drill needle and the groove cutter is also different, so it should be distinguished.

The transfer of materials needs to be confirmed and signed by two people before starting. Do not reverse the upper and lower plates, pay attention to indentation, residual glue. Remember to change the upper limit after adding the cover.

Pay attention to the position and radius of the needle. The broken needle may be due to foreign body broken needle or because the drill needle has reached the end of its service life, so the plate surface should be wiped clean when the aluminum sheet is attached to the plate.

dn is the depth of the drill plate up is the height of the presser foot.

If you really don't want to buy tools, then you can use a regular awl drill, but it's not very pretty.

You can buy a set of miniature hand drills, I just bought a set of 45 yuan some time ago, plus postage 8 yuan to supplement: that set of miniature electronic tools with cutting, if you don't want to buy it, then use the iron ruler and the boundary knife (the kind of retractable blade),

You can use a strong cutting knife, low cost, environmental protection and health, convenient and fast, find a baby in **: cutting tools strong hook knife, Xiao Chen accessories store has, it is really easy to use.

It's better to use a circuit board drilling machine and program it yourself, it will look good, it will be delicate, and it won't be too rough!

First of all, the smaller the diameter of the drill bit, the more susceptible to external force bending and bending.

1.Generally, in the slot of D l 2, the force point of the second tool drill bit is uneven, so that the slot is offset to the counterclockwise and positioning hole.

2.Under normal circumstances, the position of the loose orange in the fiber digging guide hole is well matched, and the length of the program compensation groove is not required.

3.The guide hole is used to cut off the excess corners, so that the force of the groove cutter is improved and the deflection is reduced, and the guide hole diameter and position have a great impact.

4.The guide hole is generally based on the principle of trimming.

5.Basically, the spindle rotates clockwise, and the hole type is offset counterclockwise, so the program coordinates are changed upward, and the bending angle of the drill bit will only be more oblique.

One more point. Reducing the infeed may also slightly improve skew, but at the expense of machining efficiency.

PCB drilling is a copy process of PCB plate making, and it is also a very important step. The main thing is to punch holes for the board, the wiring needs to be routed, a through hole is needed, the structure is needed, and a hole is made for positioning or something; The multi-layer board is not drilled at one time, some holes are buried in the circuit board, and some are opened on the board, so there will be one and two drills.

PCB drill bits are mainly used in PCB fabrication:

PCB, Printed Circuit Board) is a printed circuit board that consists of several layers of resin material bonded together with copper foil wiring inside. There are layers.

Drilling accounts for 30 to 40% of the cost of printed circuit boards, and mass production often requires specialized equipment and drill bits.

Good PCB drill bits are made of high-quality cemented carbide materials, which have excellent characteristics such as high rigidity, high hole position accuracy, good hole wall quality, and long life.

PCB drilling refers to the operation of machining holes in a printed circuit board with a drill bit.

PCB】PCB (Printed Circuit Board), Chinese name for printed internal capacitor circuit board, also known as printed circuit board, is an important electronic component, is the support of electronic components, is the carrier of electrical connection of electronic components. Since it is made using electronic printing, it is called a "printed" circuit board.

Drilling] Drilling refers to the operation of machining holes in solid materials with a drill bit.

There is a program that can directly call up the part number, increase and contraction, and the compensation value is set to test drilling.

The needle breaker computer will prompt you.

It seems that most of the drilling machines in PCB factories now use Hitachi six-axis drilling machines.

The operation steps of drilling machine drilling are similar: first on the board, retrieve the file, find the knife, match the knife, adjust, adjust the pressure foot, set the drill tool parameters, save the disk, and start drilling, but it will still be different according to the different drilling machines used. Here are the general steps for reference:

1. Make fixed fixtures according to the size of the processing, the number of processing holes, the size of the processing holes, and the location data of the processing holes. Tighten the clamp and the automatic turntable.

2. Set the processing data in the control computer.

3. Fix the material to be processed on the automatic turntable.

4. Start the machine, and the machine will complete the processing procedures such as punching, drilling, milling, through hole, blind hole, multi-hole, high and low hole at one time according to the computer instructions and processing data.

5. After a hole is processed, the automatic drill tray will rotate a certain angle according to the set program, align the position of the next processing hole with the processing head, and start processing again. When the entire turntable is processed, the processing process is completed in one time. Remove the machined material. Reload.

6. During the processing process, the machine will immediately alarm and stop working and wait for processing. During the machining process, when the processing tool head is not sharp, the machine will also give an alarm in time to notify the replacement tool.

Precautions: The drilling machine should always keep the body and machine clean.

In fact, as long as the drilling operator has a work instruction, it depends on what the landlord is doing, the circuit board is divided into soft board FPC and hard board PCB, in short, the operation steps of drilling are almost the same, first on the board, call up the file, find the knife, with the knife, adjust, adjust the pressure foot, set the drill parameters, save, drilling, roughly like this, depending on what machine you use, the domestic machine is very simple, like Qianghua, Tianma machine You can look at the main page, there are, I hope it can help you?

Drill every day, drill every year, just don't make money! Change careers, bro.

Brother: Your question. Hehehe...We are doing drilling machines and tapping machines.
