The devil https://www.elecfans.com/news/is hiding in the details, the rarest design, It https://www.elecfans.com/news/is also the place where problems are most likely to occur. Just because an anti-static sign https://www.elecfans.com/news/is added to the PCB, the short circuit occurs unexpectedly and strangely. Let us take a look at the situation and the case today.

It’s half past three in the afternoon, the hot sun https://www.elecfans.com/news/is warm, and the east wind blows across my face.

Lili designed a PCB, and after struggling for many days, she finally sent it to a board factory to make boards.

Take off the burden, lighten the burden, and make an appointment with the male to go to the theater in the evening to watch the latest blockbuster “Embrace You Through the Cold Winter.”

The reason why hhttps://www.elecfans.com/news/is boyfriend https://www.elecfans.com/news/is called Mouse https://www.elecfans.com/news/is not because the man https://www.elecfans.com/news/is not good-looking, but because one time he got up in the middle of the night and ate instant noodles secretly. Lili found out and nicknamed him Mouse, thus replacing him. Name, make a shining exit.

bothIt https://www.elecfans.com/news/is said that a woman https://www.elecfans.com/news/is pleased with herself.

In the first moment after work, she should take care of herself and show her most beautiful side to the men.

Suddenly the phone rang.

It was a call from the PCB manufacturing factory, saying that there was a short circuit in the gerber file comparhttps://www.elecfans.com/news/ison.

If thhttps://www.elecfans.com/news/is cannot be confirmed, it will be a fatal problem.

In the first step of PCB engineering production, IPC356 inspection must be done first.

As a result, during IPC356 analyshttps://www.elecfans.com/news/is, there was a short circuit in the network above.

If thhttps://www.elecfans.com/news/is cannot be confirmed, it will be a fatal problem.

In the first step of PCB engineering production, IPC356 inspection must be done first.

As a result, during IPC356 analyshttps://www.elecfans.com/news/is, there was a short circuit in the network above.

The screenshot of the report sent by the factory https://www.elecfans.com/news/is as follows. There are 7 short circuits in total, as shown below.

PCB marked mine design, short circuit but no trace can be found

Lili stopped what she was doing, opened her notebook, and began the arduous process of finding short circuits. Except for two places where she had to force short circuits during the design, she could confirm that there were no abnormalities. , the other five short-circuit locations can’t be found even if you die.

Later, after many communications with the factory, the factory took a screenshot of the location of the short circuit. Can anyone see the difference? ET Escorts Normally, all virtual test points are at the center of the mark. White https://www.elecfans.com/news/is the location where the virtual test point occurs.

All virtual test points are in the middle area of ​​the logo.

As shown in the figure below:

Lead-free sign, anti-static sign, recyclable sign, label area and other signs.

PCB marked mine design, short circuit but no trace can be found

Introduction to IPC356 files

• A specific format formulated by the American Printed Circuit Institute, which records the network collection files of the logical relationships of the design files.

• A logical network that ensures that the gerber input by our PCB file https://www.elecfans.com/news/is conshttps://www.elecfans.com/news/istent with the file schematic.

• Compare with the physical network created by CAM software. You can review the gerb we entereder files and drilling files, whether they are conshttps://www.elecfans.com/news/istent with the PCB schematic diagram, especially the safety of network open and short circuits.

• Known as “the patron saint of design engineers and a safe station for PCB processing.”

PCB marked mine design, short circuit but no trace can be found

From the picture above, we can see that the original PCB file, the gerber file, and the factory’s task draft have the following relationship:

The GERBER file https://www.elecfans.com/news/is matured from the original PCB file.

The script for giving birth in the workshop was created using GERBEEthiopia SugarR original files.

When conducting electrical testing in PCB manufacturing plants, it https://www.elecfans.com/news/is only necessary to ensure that the physical and logical relationships between the work draft and the original manuscript are conshttps://www.elecfans.com/news/istent.

If the original GERBER file input https://www.elecfans.com/news/is abnormal, all subsequent tests will fail.

Therefore, a file presentation https://www.elecfans.com/news/is needed to simulate the principle of factory electrical test equipment, generate virtual test points, and perform open and short circuit comparhttps://www.elecfans.com/news/isons to ensure the accuracy of the original GERBER input. The IPC356 file came into being.

Why do IPC inspections need to be done?

Since the GERBER file https://www.elecfans.com/news/is exported from the original PCB design file, during the exported GERBER process, input may occur due to differences in software versions or abnormal file settings. There https://www.elecfans.com/news/is an abnormality in the physical and logical relationship between the GERBER file and the original PCB design file, which https://www.elecfans.com/news/is commonly referred to as a short circuit. Everyone knows very well what the consequences of a PCB short circuit mean.

Lili’s PCB factory made an abnormality after doing an IPC356 comparhttps://www.elecfans.com/news/ison. She couldn’t figure it out. It wasn’t until she asked her old friend Lin Ruyan that she got a clue.

Originally, when setting up the logo package, there are two options, as shown in the figure below.

PCB marked mine design, short circuit but no trace can be found

When building a library, some engineers will confuse Package symbol and Mechaniclsymbol.

1. If the newly created package type https://www.elecfans.com/news/is incorrectly selected as Package symbol, you must add pad to the package. If you do not add pad, after the package https://www.elecfans.com/news/is built, the system will report an error (but in fact, thhttps://www.elecfans.com/news/is PAD https://www.elecfans.com/news/is not needed in the package. Usually many engineers will add a pad set to 0 on a whim. pad)

2. The normal processing help type mark should be built as Mechanical symbol type. Thhttps://www.elecfans.com/news/is type does not need to add pad in the packageEthiopians Escort , there will be no false alarms when the IPC356 bidirectional switch https://www.elecfans.com/news/is short-circuited.

Settings during package production

The mine design of the PCB mark, but there https://www.elecfans.com/news/is no trace of the short circuit

After lhttps://www.elecfans.com/news/istening to Ruyan’s explanation, Lili realized that she had chosen the first option when setting up the package. An option (Package symbol) and adding a plus pad. It turns out that all the problems are caused by myself. Learn from experience, summarize experience, and travel lightly.

After confirming that there was no abnormality in the network, Lili responded to the moderator’s email from the factory. She was in a very beautiful mood, and she went to the theater humming a ditty.

In order to make it easier for her boyfriend to find her, she went to her seat early to wait for him.

When the movie was about to start, her boyfriend called her and asked where she was. He couldn’t find her. Lili suddenly stood up and saw the boyfriend looking around. , so he waved hhttps://www.elecfans.com/news/is hands impulsively and shouted loudly: “Rat, mouse, here…”

A group of handsome men nearby heard the word “rat” and ran away in all directions. Lili was left with a confused look on her face…

Thhttps://www.elecfans.com/news/is https://www.elecfans.com/news/is exactly what happened: the sign was not set up in a standard manner and the nameless network was on the board. After painstaking efforts to search, I am exhausted.I was so frightened that I broke into night sweats.
