Alicloud designer winter 09 rules design

The PCB Board designed by many people came back from the manufacturer and found it very difficult. They complained about the manufacturer's stamp, but they did not necessarily follow the manufacturer's rules. Here, I will post my personal opinions on rules according to the jiaxx rules:

According to the so-called most xx pcb manufacturer: Jia XX process standards:

In addition, the runle rules of Alium dsigner winter 09 are generally implemented by jiaxx, so you must never challenge its limits. Just like you eat 1 bowl of rice at ordinary times, but you can eat 3 bowls at most. If you want to eat three bowls at a time, you will not be able to eat any birds.

OK. Let's get started !. Because I am not that professional (installation forced), I use mm.

(1) Electrical (electrical rule), set the line spacing to 0.254mm (10mil)

(2) Electrical (electrical rule), set the copper-clad spacing to 0.4mm (jiaxx is hard to achieve a small margin, 5mm mm is not excessive, although it is worse than the line I was attacked)

(3) routing, line width, according to The jiaxx process, we do not dare to challenge the limit; due to the requirements of the power cord, We need to bold, because the following settings

In fact, many Board gods like to take VCC And Gnd special treatment, create a new width, set the width of VCC And Gnd, I personally think it is OK, as long as you know it in your mind.

(4) passing through the hole. According to jiaxx's technology, although he called passing through the hole for a limited time of 0.3mm, but according to my many years of attempts, it is purely a suicide behavior. Sometimes passing through the hole cannot pass through the hole, for our board to live well, but also for our drawing board workload will not be too large, compromise, many tests, 35mm diameter, 65mm diameter no problem so far:

(5) The pattern of plane pad is used to prevent heat loss during welding, making the welding more refreshing. The default value is as follows:

(6) When some high-frequency boards, boards for switching power supply, or boards are very large, the upper and lower two-layer boards (for example, double-layer boards) must be opened through holes to increase the conduction rate, yes, more stable potential between the Earth and the ground, and some other features (I checked them online), but these passing holes can be non-pattern, because we do not need to weld

(7) Manufacturing holesize I don't know if this is a duplicate, but it is useful. The following settings

(8) to facilitate our integration design, we can directly set the value to 0 if there is a Red Hook:

(9) I have many other skills. I will try again later. I am busy with logic...

I do not challenge people's limits. I have come to this day step by step. except for occasional errors or the last gold-plated board is over, there is generally no big problem.

However, the quality of jiaxx is indeed poor, but what is the solution ??? People are cheap...

So many people say how jiaxx is poor and how can it be done? I don't agree very much. As long as you follow his standards and don't challenge his limits, it's okay...
