Today is destined to be a busy day for Sifang Factory.

In the afternoon, after Luo Shouwu negotiated with several old comrades, they made concessions on behalf of the factory.

Niu Lao and other representatives of the factory re-signed a supplementary agreement, before the chip supply is not normal, the purchase of remote control circuit boards is postponed indefinitely, but once the supply channel of the Sifang factory is stable, within one year, Niu Lao and their respective factories can purchase remote control circuit boards at a price of 95% off the market price as compensation.

In the evening, the director of the joint venture factory Ma personally came forward to negotiate with other color plant procurement personnel to solve the problem, but because the two sides had too many differences, it finally became a deadlock.

This time the main material supply outage incident is tantamount to a slap in the face for the Sifang remote control circuit board of the joint venture factory that is just about to open the sales situation, and it also makes the Sifang management clearly realize the importance of independent and controllable and multi-channel supply.

In the evening, Yu Zixian, Liu Jian, and Wei Xianglin left to fly to Pengcheng.

Before leaving, Yu Zixian got the only news that he was glad about, Jiang Lao really found a place where he could tape out 3-micron process chips in small batches.

This news made Yu Zixian overjoyed and surprised at the same time, when did there be such advanced technology in China?

Jiang Lao only said: "It's just a special case, it's not that we have broken through this technology." "It's just that we can't stress enough that we must keep a low profile and keep it confidential.

Thinking about it, Yu Zixian could only think of one thing, that is, what came in through secret channels.

In the case of the technological blockade of the republic by the United States and Europe, but there will always be one or two breakthrough points.

In addition, 3~5 micron technology has been introduced into China for many years, and there has been a lot of research on the current 1.5 micron chip processing technology.

Mass production is unlikely, but it is possible to do it in a laboratory state if there are a few key pieces of equipment.

In fact, Yu Zixian doesn't want much, just a few sample films.

Now that Jiang Lao dares to say this, he must have been quite sure.

Yu Zixian has not had much confidence in whether the previous plan can be completed, but he has to fight with the knife holder around his neck, and now he has a little hope in his heart. At least now you don't have to hang yourself on a rope, you have to find a foundry over there.

However, it is still necessary to do both at the same time, just in case.

Now Yu Zixian can go to Xiangjiang with confidence.

It's just that the time is still very tight, and the material reserves of the joint venture factory are only half a month, even if there is a delay in supply, but it will take up to three weeks, if the chip still can't solve the problem, then only the production line will be stopped.

After deducting the one week required for chip transportation, Yu Zixian was given only two short weeks of time, and in these two weeks, they had to complete the simulation, verification and trial production of Toshiba's TM50536 chip imitation version - SF51991 version (Sifang imitation optimized version), as long as it was successful, even if only one chip was OK, it was done!

But fortunately, now he is not struggling alone, but people on both sides are struggling.

Yu Zixian is responsible for the success of the EDA of SF51991 chips, and Jiang Lao is responsible for contacting and coordinating the production trial production.

In these old comrades, Yu Zixian once again felt the spirit of wholeheartedly doing the revolution depicted in the book!

By the time Yu Zixian and them passed through Pengcheng and arrived at Xiangjiang, it was almost noon the next day.

However, the three of them didn't have time to rest, so they went directly to the research center of the headquarters of Lu's Group.

There are already people docking here, and the chip information will start working as soon as they get it.

The circuit information layout is entered into the graphic design system, and the professional diagram form is generated, and then connected to the IBM minicomputer installed with the simulated SPICE simulation software EDA.

This kind of imitation chip design re-simulation is the last inspection before the wafer is put into production. There are naturally more problems in the first inspection, and as the problems are gradually modified and improved, the problems reported by the simulation will only become fewer and fewer until the problem is zero.

Wei Xianglin stared closely at the simulation report on the screen and said what it was, and Yu Zixian listened and sat and recorded.

Design Rule Check ......

"Appliance Rule Check ......"

Performance Simulation ......

In the past three days, Yu Zixian, Liu Jian and a group of engineers arranged by the Lu Group to help modify the chip problem began to fight with the bugs reported by the simulation software.

Yanjing Sifang Factory, after Luo Shouwu came forward, temporarily ended the three-day stalemate with the buyer.

After the Sifang Electron Tube Factory made a concession of 9.5% off the factory price and lasted for one year, most of the manufacturers expressed their understanding and were willing to accept it; however, nearly half of the manufacturers still insisted on not giving in and asked the Sifang Electron Tube Factory to deliver on schedule, two of which were still large orders, and the orders of the two factories in two months combined were nearly 200,000 sets.

Luo Shouwu gritted his teeth and shouted in public: "In the future, we will not do the business of Hongyang Color TV Factory and Caili TV Factory in Sifang Electron Tube Factory!"

Just two days ago, the joint venture factory got in touch with Toshiba's Yanjing headquarters, and yesterday Toshiba also gave a message reply, putting forward two points: "Either accept the fact that the price of TM50536 chips has risen by 100%, from the original 32 yuan to 64 yuan, or accept Toshiba's capital injection and become a major shareholder." ”

According to the agreement signed between Lu's Sifang Industrial Company and the purchasing units, even if the highest price is 130, if the price of TM50536 chips rises from 32 to 64, then the joint venture will lose 2 yuan for each set of production, not to mention that the average selling price is about 120 yuan.

Another plan proposed, Toshiba's joint venture factory, which now has 10 production lines and nearly 1,000 skilled workers, is estimated at only 8 million yuan. According to the previous two combined cash investment, it has exceeded 8 million, not to mention the more than 1,000 skilled workers, the most important thing is that according to the current hot market of remote control circuit board market, the valuation of 6 million is simply insulting. According to Yu Zixian, with a valuation of 15 million less, everything is not to be discussed.

If you make money for nothing, you have to lose money, of course Luo Shouwu won't do it! The alliance under the city, Luo Shouwu doesn't plan to sign it!

So in a fit of rage, all the other manufacturers who insisted on due delivery were blacklisted. As long as this joint venture factory survives this catastrophe, they must be good-looking!

They couldn't figure out how Toshiba would dare to forcibly come to the door to make a purchase, wasn't this a robbery by Hongguoguo? If they had done it before, they would have done it first.

But now that the times have changed, they have begun to pay attention to economic benefits, and their previous set seems to be a little unproductive!

After all, I want to think about it, this time the feeling is really uncomfortable!

However, this also completely aroused the anger of Luo Shouwu and Niu Lao and other old men.
