Introduction: Laser Printed PCB's, Perfect and Easy.

这里可能没有什么新的,但我想分享我打印的方式,这不是如此简单的PCB始终完美,没有一个故障。

第1步:电路设计。

我总是在面包板中模拟电路,以确保一切正常工作。我将使用相同的组件进行最终电路。

第2步:建模。

为了设计PCB,我首先在Proteus中模拟电路,一旦一切正常连接,就可以启动轨道设计,确保轨道尽可能宽。手动调整轨道对此目的是有用的,有时也需要重新路由。不要坚持自动设计。

步骤3:打印电路布局。

激光打印电路在薄光泽杂志上是至关重要的(大多数报摊杂志的普通纸)。通常,这种纸太薄,激光打印机处理,所以我将它带到常规纸上,这样它就能正常工作。小心不要打印镜像设计,只需打印铜侧艺术品。

Step 4: PCB Preparation.

将板切割成所需的尺寸,以及印刷布局。尽量不要用手指触摸印刷表面,用边缘处理纸张。通过超细砂纸或金属羊毛用纯丙酮用纯净的丙酮清洁板的铜侧。现在,您可以将印刷纸和董事会放在一起。

第5步:布局转移。

在纸张顶部放置冷常规服装铁。铁温应设定在大约120摄氏度左右,不要太冷或更热(在我的铁中,它是丝绸设置,或尼龙和聚酯设置之间)。这个想法只是为了使墨粉柔软粘稠,但不能融化。用铁在原地上转动,而不移动,只需施加压力即可到达温度设定。然后,我开始将铁的圈子施加施加温和的压力三到五分钟。最后,您将注意到电路设计通过纸张。关掉铁,让PCB冷却一段时间。

Step 6: Finishing the Transfer.

Once cool, place the PCB in a tray with water. After just a few minutes you will notice that the paper turns loose and the toner has transfered completely to the copper. There is no need to rub the paper to remove it. The PCB is then ready for the chemical treatment.

第7步:PCB精加工。

The PCB con be treated chemically for copper removal by your preferred method. I use ferric chloride but a mixture of muriatic acid and oxy-water also works. Once the etching process finishes (between 20 and 30 minutes), remove the toner with acetone. I use a 0.8 mm drill bit for all the holes and then a 1 mm bit for the larger electronic components. This way the finished circuit works perfect without the need to rework the tracks in any way.

你有没有考虑使用其中一个廉价的Pantum P2500系列黑白激光打印机,用于直接印刷电路板?

Peroxide from pharmacy and baker's citric acid powder works like a charm for me. 100 ml 3% H2O2 + 30g citric acid + 5g NaCl (salt), mix thoroughly, don't drink. And surely make use of it while it's fresh and warm.

How fast is it with 3% Peroxide? I have seen it on you tube only with concentration like CharlyeZ and 36% HCl?

The maximum in Germany is 10% H2O2, above is restricted like HNO3(Terrorism etc)

嗨!我(芬兰),一个旧计时器,让他们成为PCB的。我已经制作了“数百(100年)的人,因此今天仍然使用”旧金系统“1 + 2 + 3甲豆
1 = HCl(36%),2 =氢过氧化物(25%),3 =水(100%)。

()中的数字是东西的浓度。

For the developeing of the photoresistive I use NaHO, (Natrium Hydroxide).

Make a trip to Finland, (it is within the EU), and make your purchase of them needed chemical's here, them "Custom's" will just wonder "What the f***" is this" and you just reply: " It's for scientyfic purposes"... "Hmm... OKAY"

Yep, with fresh peroxide in warm water it takes less than 20 mins for small pcb's. No dangerous HCl needed. The chemistry behind is
Cu + H3cit + H 2 O 2→H [CUCIT] + 2H2O

你好,

using the similar mix, but60%HCl + 30%H 2 O 2 + 10%H2O.

工作比氯化铁更快。

Concentration:

HCl - 36%

H2O2 - 26% - technical

H2O 100% - (不要从核电站使用重水..... :-)))

Hi. Just allmost the same here. I use a ”thumb-formula” 1+2+3
but the other way around of your’s: 1 part of HCL, (acid 35%, 10ml),
2部分H 2 O 2(60%),(HYD ..超氧化体,20mL)和3份H 2 O 30ml水,(约100%)从水龙头或天空中。像魅力一样,关心:你需要遵循这个过程,因为它会在此期间快速且越来越温暖。一直使用手套
换气的盐酸(35%),和生存。在草原t, (if you survive, you’ll remember that smell for the rest of your life), you’ll understand the necceserity of using gloves.
我错过了一次,在我的不锈沉陷上有几滴掉落。他们的痕迹泄漏将留在那里“Forewer”。I’ve etched PCB’s with both methodes ”FeCl” and ”HCL” , to me: I prefer the HCL-methode => fast & clear, (during the process you can whenewer pick up your PCB and rince it under running water and study the result, (as well with the Fe), and if not good => back into the bath). Check me what I’ve complissed at: www.teksel.net

I am actually way past even double sided PCBs anyway. Did that back in
the 70s, quite successfully. Electronics and computers are of little
兴趣超越工具,以获得其他事情。很多我会的
已经完成,这些天可以用Arduino完成。我的下一个很实质
project requires multiple, high efficiency multiphase, isolated Buck
converters. That will need 4 layers.

你仍然取消,从而使它们为4层......猜测您从制造商订购它们?

CAUTION! If you choose to use acid/hydrogen peroxide mix for etching, be sure you COMPLETELY rinse it off with running water, then dry COMPLETELY, before applying the acetone. If you don't, you can accidentally end up with acetone peroxide, which is EXPLOSIVE!

NEVER allow acetone to mix with hydrochloric acid and hydrogen peroxide!

所以你在一个报摊纸上打印。
But the ink on the newsstands will not transfer also when you apply heat ?

用于在印刷线路板上蚀刻铜的通常商业过程(因为它们被正确调用,因为没有电路,直到组分焊接)是含有氯化物溶液的碱性氨。

WHAT?? Go and pick up Your Nobel-price, because if You invented the production of caps, inds, antennas, res, by simply print them on a copper-laminated fiber-glass board... You'll be a bllion-zillion-quad-zillionarer

Not sure about capacitors or resistors, but inductors and antennae can be printed directly on the PCB and they're quite common.

Suraj, OK You’r right about making them antennas and resistors right printed on the PCB.
BUT, keep in mind the ”wery…wery…” complicated calculatioin formula when doin’g that.
Antenna: (there’s a ton of litterature on that subject), act’s as a transmitter or as a receiver or them both at the same time. In all cases You have a net of capacitance + resistanse that creats inductance. This can be measured either, (or many), as a differential behaveior of electrons flow from source to drain. You can make this antenna on a PCB if you follow the next: the thicknes of your copper layer (including the concideration of the purity of the copper, it can wary some of 29% to99%), x the depth of You’r copperlayer, ( it warys ??/ ounches) x the lenght of your trace, (mils, or thou’s), Calculate THAT at first, and you get some resistance. And then calculate the capacitance of the same. And then calculate the total impedance. And then evaluate a formula of it all. Excel could do that for you if you tell it the right formula.
Good luck

都很有用,谢谢!但它超出了我们只有凡人的手段,他们真正需要做这样的东西......我想想在现在可以在某处有一个企业,你可以在哪里发送设计,他们会发布它对于合理的价格给你?

我现在真正探讨的是一个电路板,用于呼吸/淡出/衰落/褪色的LED或LED,但是尽可能多地耗尽3伏....我只是在这里发布,以防任何人都知道我如何才能订购一个?

但这是令人敬畏的工作,谢谢你的发布!
