Chapter 3: Resurrection Overture (III)

Qi Leren stood in front of the door that had once made him beyond salvation.

After the huge stone door, Maria’s sword was held high and the black dragon was crucified. Seven days ago, there was a former friend sitting on the throne that belonged to the Pope, smiling at him.

Now that I think about it, I still feel like I had a nightmare.

Worried that there was some unknown danger inside, Qi Leren removed "Devil Etiquette", changed it to the perception skill "Rain-Day Clothing", put his hand on the stone door, and pushed it gently. The stone door opened almost automatically before his eyes.

Maria and the black dragon were still there, but the metal sword in Maria’s hands had ceased to exist. Qi Leren's eyes fell to the blood on the ground, and the dragged blood seemed to bring back the scene before his death.

He took a step and wanted to go there, but the first step made this dead and broken church glow with incredible changes—

The statue of Maria exuded bright light, and countless cracks spread from its head. Qi Leren stared at this horrible scene and the cracks became more and more dense, spreading from Maria to the immortal body of the black dragon. The two statues with a height of more than ten meters were destroyed in an instant by time, turning into countless fragments and dust that poured down, rushing to the earth like waterfalls!

The entire site of the Vatican collapsed in a frantic tremor.

During this collapse, Qi Leren, who had been knocked down by the shock wave, looked towards the Maria.

Maria's phantom stood there, holding an object that seemed to be a scepter in both hands and coming towards him.

The ground shook so much that Qi Leren couldn't stand up at all, but Maria's phantom came to him as if on flat ground and handed the thing in her hand to him: "Please, bring this to the Prophet, you must give it to him personally."

"Who is the Prophet? Where is he?" Qi Leren asked, confused.

"He is in the judge’s seat of the Twilight Township. If you meet Ning Zhou, don't let Ning Zhou touch this thing and don't let him see it," Maria said.

Qi Leren looked down at what Maria gave him and held out his hand. The name of this item was [Scepter of Hell], which was made of metal, heavy and dangerous. There was a huge groove at the top of the scepter and the gem originally embedded in it had disappeared, leaving only this metal scepter with evil power. This was an extremely powerful and fearful demon item, which can even pollute the power of faith.

"I understand, I will give it to the Prophet." Qi Leren understood that the matter was important, so he put away this scepter and solemnly agreed.

"Thank you." Maria smiled, leaned over Qi Leren, and left a gentle kiss on his forehead.

The gentle kiss was like the blessing of God. Countless golden and silvery spots spread from Maria and she began to become blurred. However, these spots rushed into Qi Leren's body and he suddenly felt himself immersed as if in a hot spring. The warm energy soothed his stiff and tired body, injecting vitality and vigor into him again.

Indulged in this comfortable power, Qi Leren forgot where he was until an angry roar came from above: "How dare you! Maria! Again and again you have... I will not let you go!"

The Witch of Desperation, who found the body of the Devastator destroyed, roared. Storm clouds condensed with thunder and lightning and the terrible demon energy brewed the power of death. Countless bats came at them!

Maria nodded to Qi Leren languidly: "Good boy, go, remember my words."

Saying this, a bright white light rose from Qi Leren's feet, pierced through the dark clouds in the sky, and wrapped around Qi Leren to fly him towards the distant land of dusk.

In this dazzling silvery white light, Qi Leren felt his body float uncontrollably just like in the dream before, rising higher and higher, and the white world was full of magnificent and majestic vitality, solemn and quiet. Wrapped in the holy light, he flew in the sky like a gliding bird, moving forward in a pure white.

Suddenly an ethereal music sounded ahead. Qi Leren woke up from his dreamy state and looked in the direction of the music.

Countless little angels with flowers and musical instruments in their hands flew out of a magnificent gate, joyfully spreading petals and playing graceful music. That gate seemed to be the door to Eden. From the open gate, he could see a garden full of flowers. Angels holding musical instruments were playing the piano and singing songs by the fountain, singing praises to Father God.

A petite young female angel came out of the garden and her feet lightly landed on the clouds, smiling at Qi Leren.

Qi Leren tried to see her face clearly, but she seemed to be a light-year away from him.

"I am the Prophet," she said. "Give it to me."

Qi Leren's eyes were empty and that person's voice seemed to be God's will, which made him want to obey her orders involuntarily.

Give the Scepter of Hell to the Prophet, and she is the Prophet... This was firmly rooted in his mind.

Qi Leren took the Scepter of Hell in his hand without thinking.

[Rain-Day Laundry: At present, the remaining sensing times are 2/3.]

Qi Leren suddenly woke up. How could he believe that this unknown person was the Prophet?! This brainwashing power was simply terrible! He almost handed over this thing!

"Hmm?" The angel on the other side let out a confused hum as the projection of an archangel emerged behind Qi Leren, holding a rapier to cut the heavenly gate.

In a blaze of holy light, the world was silently torn apart and all the dreamy things in front of him disappeared in an instant.

Under the curious gaze of hundreds of millions of human beings and demons, this white holy light that shone in an arc across the sky paused for a moment in a cloud of black mist, then pierced the darkness and continued to fly towards the Village of Dusk on the eastern coast.

In the garden of Dawn.

"An unexpected miss. It’s not enough to use the avatar projection in front of him, I was too hasty," the petite woman sighed.

"You can't stop using the field’s power. After all, it’s the last of the Holy Nun’s power," the man taking a slow sip of wine said lightly.

"But to use ‘Utopia’, it will be weakened after being pierced by that holy light, it’ll do more harm than good. Forget it. Anyway, I already know that thing’s whereabouts, I’ll just ask others to keep it for the time being," the woman said and smiled again. "But that child you like is quite vigilant."

The red wine in the goblet was swirled gently, its thick red color like blood.

"People with secrets will always be more vigilant. I really wonder how many secrets he still hides."

The Village of Dusk on the east coast was shrouded in the afterglow of sunset all year round.

On the long coastline, Chen Baiqi was smoking on the seawall and her sister Sissi was catching crabs. Suddenly, she found a shiny stone. She screamed with surprise and took the stone to Chen Baiqi: "This is beautiful, I want to show it to Xiaozhi!"

Chen Baiqi glanced at the stone, but it was only a rare sea stone. She rubbed her sister's hair: "Okay."

"But I haven't seen Xiaozhi for a long time." Sissi was worried about her little friend. "Is it the Prophet who won't let him out?"

"Maybe," Chen Baiqi replied absently, full of melancholy. "We’ll go home in ten minutes and go to the Undead Island in the afternoon."

Sissi cocked her head and suddenly realized: "Is it Qi Leren’s seventh day?"

Chen Baiqi responded gently and let out a sigh.

The little girl who didn't know her sister's worries kicked the sand under her feet and muttered, "Why did he die?"

"People will always die," Chen Baiqi said lightly.

Sissi felt her sister's heavy heart and took her arm obediently. She was well protected by Chen Baiqi, but that didn't mean she didn't know anything. She had met many of Chen Baiqi's customers. Those young men and women came to her store to buy what they needed. Some of them came very often while others came rarely, but gradually these people disappeared.

Those who had disappeared had never returned again. There would always be new faces coming and disappearing like those people.

Sissi remembered that when she was a little girl, a beautiful little sister always brought her delicious candy which was wrapped in colorful cellophane, and each one was sweet. She loved the candy brought by that little sister. Every time, she had collected these beautiful candy wrappers and put them in a small tin box until she had saved a whole box.

Then one day, when she saw the tin box, she suddenly remembered that she had not seen the little sister for a long time. She asked Chen Baiqi several times, and Chen Baiqi was silent for a long time, saying that she would help her find out.

She happily went back to her room, folded a string of paper cranes with those cellophanes, and prepared to give it to the little sister.

But in the end, she could only give the folded paper cranes to her tombstone.

On the Undead Island, which was just outside the Village of Dusk, the warm sunlight had illuminated her tombstone with her name on it and the days she had lived. There were only two simple lines that summarized a person's short life.

She had felt that she wasn’t very sad, but at the thought that she would never eat that delicious candy again, she had burst into tears.

Later, she learned where to buy this delicious candy that tasted sweet, but it wasn't from that little sister, so she didn't like it anymore.

She thought that, in fact, she didn't like that kind of candy very much, she just missed the little sister.

It was a carefree little girl who taught her the meaning of death for the first time.

"Jiejie*, you seem to have liked him very much?" Sissi asked.

*{E/N: “older sister”}

Chen Baiqi smoked a cigarette and the smoke blew away in the sea breeze: "Because a friend of mine likes him very much."

"How much did you like him?" Siss smiled and asked, "Does jiejie like me so much?"

Chen Baiqi looked at her sister's innocent face, smiled, and kissed her face: "Maybe I liked him more than jiejie likes you."

Sissi gave a "wow": "You must’ve liked him very much."

However, Sissi was a little sad again: "How sad will your friend be now that he’s dead?"

Chen Baiqi could not speak and her hand holding the cigarette was shaking. There was a little bit of sweet pain in the sour despair; even if it was just a bystander like her, she was almost suffocating.

She wouldn't be able to forget for the rest of her life. On that rainy day, Ning Zhou, who had gone to the Holy City with Qi Leren, suddenly returned to the Village of Dusk and knocked on her door. She was puzzled, but was shocked by Ning Zhou's calm dead eyes. Ning Zhou had braved the heavy rain and told her what had happened. Then, despite her dissuasion, he resolutely went to Neverland. He didn't even know whether he could survive the torture of the spiritual enchanment, or if it would leave him sleeping in the cold tundra forever.

Fortunately, Ning Zhou's tombstone had yet to appear on the Undead Island. It seemed that he had successfully arrived at his soul’s former hometown, bid farewell to it, and went to a world full of thorns and sufferings.

Thinking this, she suddenly heard Sissi let out a loud scream. Chen Baiqi raised her head and looked at the sky in astonishment—in the far west, there was a bright light streaking across the sky, magnificent, holy, and unparalleled, and all the places it passed were the projections of heaven. It stopped over the Village of Dusk and turned into a vertical beam of light.

A huge projection of an archangel appeared in the void, behind which countless wings danced slowly in the setting sun, almost covering the sunset. The wings were dying, like a white rain, and the projection of the archangel was getting weaker and weaker. He put his hands on his chest, bowed toward the distance, and disappeared into the golden red sunset.

Sissi was stunned. After being shocked, Chen Baiqi’s mind suddenly raised countless thoughts: Which of the Holy See's field-level masters had come to Dusk? The place of arrival also happened to be in the spot where the Prophet had landed at dusk... No, it should be just residual energy. If it was really a field-level master, they would not reveal such a big movement at all. And the Court’s enchantment has not been alarmed... Who was it?

"Sissi, go home, I'll check it out and I'll be right back," Chen Baiqi said, and inserted a card into her card slot. A projected book turned to a certain page in her hand. A white unicorn appeared beside her and she turned around to mount the horse. The winged unicorn flew in the air to the place where the projection of the archangel had landed.

She arrived at her destination in less than half a minute due to the short distance. On the rolling sea waves of the beach, a confused figure was looking in all directions at a loss. Seeing Chen Baiqi approach, he waved at her in surprise and ran quickly to her.

Chen Baiqi's cigarette butt fell to the ground, and shock and joy were intertwined. She couldn't wait to express her incredible mood with 10,000 swear words: "Shit Qi Leren, aren't you fucking dead?!”

What is PCB proofing?

The so-called "PCB proofing" refers to the trial production of printed circuit boards before mass production. It is mainly used by electronic engineers to design small circuits and complete PCBs, and then carry out small-scale trial production to the factory. To our knowledge, this process is "PCB proofing" before confirming the product design and testing the product design. PCB proofing detailed process:

1. Contact the manufacturer

First, you need to inform the pcb manufacturer of the documentation, process requirements and quantities. Take Rigao Electronics as an example.

2. Opening

Purpose: According to the requirements of the engineering data MI, it is cut into small pieces on a large sheet that meets the requirements to produce a panel. Small sheets to meet customer requirements.

Process: large piece → cutting board according to MI requirements → simmering plate → beer loin \ covering → plate out

3. Drilling

Purpose: According to the engineering data, the required holes are drilled in the corresponding position on the plate that meets the required size.

Process: laminated plate pin → upper plate → drilling → lower plate → inspection \ repair

4.Shen Tong

Purpose: Copper immersion is used to deposit a thin layer of copper on the walls of insulating holes by chemical methods.

Process flow: rough grinding → hanging plate → automatic copper wire → lower plate → immersed in 1% dilute sulfuric acid → thickened copper

5. Graphic transfer

Goal: Graphic transfer is to transfer images from production film to board

Process: (blue oil process): grinding plate → printing the first side → drying → printing the second side → drying → exposure → imaging → inspection; bit → exposure → still image → inspection

6. Graphic plating

Purpose: Pattern plating is the plating of a copper layer and a gold-nickel or tin layer on a bare copper skin or hole wall of a circuit pattern.

Process: upper plate → degreasing → secondary washing → slight corrosion → water washing → pickling → copper plating → water washing → pickling → tinning → water washing → lower plate

7. Peeling

Purpose: To remove the anti-plating layer with NaOH solution, and expose the non-circuit copper layer.

Process: water film: insert frame → soak alkali → rinse → scrub → pass through the machine; dry film: put the plate → pass through the machine

8. Etching

Purpose: Etching is to etch away the copper layer of non-circuit parts by chemical reaction method.

9. Green oil

Purpose: Green oil is used to transfer the pattern of green oil film to the board to protect the circuit and prevent tin on the circuit when soldering parts.

Process flow: grinding plate → printing photosensitive green oil → translation plate → exposure → shadow; grinding plate → printing first side → baking plate → printing second side → baking plate

10. Character

Purpose: Provide characters as recognizable marks

Process: When the green oil is finished, let it cool, place it on the screen, and print the characters.

11. A gold-plated finger

Purpose: Nickel / gold plating on the fingertips of the plug, and plating according to the required thickness to make it harder and more wear-resistant

Process: Upper board → degreasing → cleaning twice → micro-etching → cleaning twice → pickling → copper plating → cleaning → nickel plating → cleaning → gold plating

12. Tin plating (co-located process)

Purpose: Spraying is to spray a layer of lead-tin on bare copper surface not covered with solder resist oil to protect the copper surface from corrosion and oxidation and ensure good soldering performance.

Process: micro-etching → air drying → preheating → rosin coating → solder coating → hot air leveling → air cooling → washing and air drying

13. Shaping

Purpose: To produce the shape required by the customer by stamping or CNC gong. Organic gong, beer board, gong, hand cut

Note: The accuracy of the data gong board and beer board is higher, followed by the manual gong, and the manual cutting board can only be made with some simple shapes.

14. Testing

Purpose: Through electronic 100% test, to detect open circuits and short circuits that are not easy to visually detect.

Process: upper mold → release plate → test → pass → FQC visual inspection → unqualified → repair → return test → OK → REJ → scrap

15. Final inspection

Purpose: 100% visual inspection of the appearance defects of the panel, and repair minor defects to avoid problems and outflow of the defective panel.

Specific work flow: feed → view data → visual inspection → pass → FQA spot check → pass → package → fail → process → check OK

Rigao Electronics is committed to providing customers with the best prices, the highest quality products, the fastest delivery times, the most professional engineering support and the best after-sales service for customers worldwide.

Knowledge of connectors (2)

First, the plating of the connector

The electroplating of the connector is mainly the electroplating of the conductor part, such as PIN, wire end terminal, grounding piece, etc. The main function of electroplating is to prevent oxidation of the surface of the conductor, improve corrosion resistance and protection performance.

Electroplating definition:

Electroplating is to immerse an electroplated piece (product) in a syrup containing metal ions to be plated, and turn on the cathode. The other end of the syrup is placed on a suitable anode (soluble or insoluble), and the surface of the plated part is passed through a direct current. That is, a method of depositing a metal film.

Common plating materials:

Nickel plating: use for bottoming, improve corrosion resistance, thickness is usually 50u"Min.

Tin plating: Improve welding ability, divided into 2 kinds of tin: bright tin and fog tin. Bright tin is not resistant to high temperature, suitable for DIP products; matt tin high temperature resistance, suitable for SMT products.

Gold plating: improve the conductive contact resistance, improve signal transmission, high cost, generally with selective plating gold.

There are two methods of electroplating: first plating and first plating and first plating. The first plating is usually used for electroplating of terminal terminals.

There are two welding methods for board connectors: wave soldering and reflow soldering, all of which are automatically soldered by machine.

The welding process and temperature profile of the two are different:

Wave soldering is used to solder DIP type board end connectors, the maximum temperature of soldering is 240 ° C;

Reflow soldering is used to solder SMT type board end connectors, the maximum temperature of soldering is 260 ° C;

Second, the connector's three characteristics test

1, Mechanical properties

1.1 PIN retention

1.2 The pull-out force of the wire off the terminal cover

1.3 Insertion force between terminal and HOUSING

1.4 Pulling force between terminal and HOUSING

1.5 whole set of insertion force and pull-out force

2, Electrical performance

2.1 Contact resistance

2.2 Insulation resistance

2.3 Withstand voltage

2.4 Rated current and voltage

3, environmental performance

3.1 Durability test

3.2 Temperature rise test

3.3 Cold resistance test

3.4 Salt spray corrosion resistance

3.5 constant temperature and humidity

3.6 Thermal shock

3.7 Solderability

3.8 Solder heat resistance

The above is a superficial view of Konnra Electronics. You are welcome to participate in the additional discussion. Subsequent will continue to update the knowledge of the connectors, thank you for your review.

Precautions for operating the fully automatic immersion tin machine

Even with automatic tin immersion machines, safety accidents may occur during use. In fact, most of these accidents are caused by human factors. As the basis of enterprise production, safety must be ensured, and at the same time, efforts must be made to reduce the operational risks of automatic immersion tin machines.

First of all, it is necessary to strengthen the safety awareness and operation mode training of the operators; although the automatic immersion tin machine automatically completes the production of the terminal, the installation of the knife and other links still needs to be completed manually, and must be carried out by professionals after the installation, and testing must also be carried out .

In order to improve the safety of the automatic immersion tin machine, it is necessary to ensure that the power supply is disconnected when the processing wiring harness is replaced, and the power supply cannot be replaced while the machine is running. This is a very irresponsible performance. After the automatic immersion tin machine is produced, the surrounding environment and the cleaning and trimming of the equipment itself cannot be ignored, so as to avoid safety accidents caused by residual materials at the edges and corners, thereby improving the safety of the automatic immersion tin machine.

Common faults and solutions of immersion tin machine

The automatic immersion tin machine is an indispensable special equipment for the production and processing of various cables and wires. It is a professional and intelligent high-end technology enterprise product separated from the laser cutting multi-function machine. It is basically not manual operation in actual operation. , But also malfunctions. Haisheng introduces you to several common faults and solutions of immersion tin machine.

The cutting length of the electronic wire of the automatic immersion tin machine is different

1. The wire drive wheel is too tight or too loose. If this phenomenon causes problems, we only need to use the rolling line to rotate to adjust the gap between the two wheels, so that the cable is not flattened, too loose and cannot fall off. This mechanical failure can be completely resolved;

2. The straightening device is too tight or too loose. If due to this problem, our correct handling should be based on the basic principle of being able to play the role of the straightening device and successfully complete the delivery, in order to completely solve it;

3. Cutting edge damage or edge, in this case, we only need to remove and replace with a new tool.

Machines and equipment cannot run or stop in rotation

First check whether there is current input, and then check whether the total number of settings is reached, whether the wire or an operating part is stuck, and then check whether the automatic immersion tin machine has a signal connection or a power connection, so that the immersion tin machine does not press down.

The points for attention when operating the automatic immersion tin machine equipment and the solutions to common faults are the above. I hope to help you. If you have more questions about the automatic immersion tin machine, please consult us.
