DIYReprap3D打印機(jī)主板

你需要一個(gè)焊接工具和SMT焊接工具，構(gòu)建該板。 This board contains surface mount parts.該電路板包含表面貼裝部件。 The hardest part about SMT soldering is getting over your fear and staying calm.關(guān)于SMT焊接最難的部分是在你的恐懼和保持平靜。 完全初學(xué)者沒(méi)有任何問(wèn)題。 There are four parts to building a surface mount board using the Hotplate Reflow Technique :有四個(gè)部分，建設(shè)表面貼裝板采用回流焊爐技術(shù) ： 1. Apply solder paste to every exposed SMD pad應(yīng)用焊膏每SMD焊盤裸露 2. Place each SMD component on its appropriate pad其適當(dāng)?shù)膲|放在每個(gè)SMD元件 3. Place populated board on a cold hotplate.在一個(gè)寒冷的烤盤放置填充板。 Turn hotplate on.打開(kāi)烤盤上。 Board solders itself!董事會(huì)焊料本身！ 4. Solder in remaining through hole components.通孔元件焊錫剩余。1. 1。 Apply Solder Paste 應(yīng)用焊膏 Okay, so this part is pretty easy: get your solder paste syringe and start applying solder paste to every SMD pad.好了，這部分是很簡(jiǎn)單：讓你的錫膏注射器并開(kāi)始應(yīng)用到每個(gè)焊膏貼片墊。 I like to use a squeeze/tap method.我喜歡用一擠/水龍頭的方法。 That is, I squeeze a bit of solder paste out, then tap the place where it goes, rinse and repeat for every exposed pad.也就是說(shuō)，我擠了出來(lái)焊膏位，然后點(diǎn)擊它去的地方，干凈，并為每個(gè)裸露焊盤的重復(fù)。 Do not put solder paste on pads with holes in them.不要把與焊接墊貼在破洞。 Youll solder those in step #4.您將在步驟4焊料的。 In order to get the right amount of solder paste on the pads for the small TQFP parts, use your finger to smear the paste like shown in this picture.為了讓青少年對(duì)小TQFP封裝的焊盤部分焊膏適量，用你的手指涂抹像這張照片顯示粘貼。 It looks ugly, but youll get much fewer solder bridges this way.它看起來(lái)丑陋，但你會(huì)得到多少這樣少焊橋梁。 2。 Place Components 放置組件 This is probably the trickiest part, but its not too bad once you get the hang of it.這可能是最棘手的部分，但它不是太糟糕了，一旦你熟悉了它。 The nice thing is that if you mess up, you can reposition the component all day.好事是，如果你陷入困境，你可以重新定位元件的所有日子。 You can even wipe off the solder paste and start over if you like.你甚至可以擦掉焊膏和重新開(kāi)始，如果你喜歡。 Very forgiving to the beginner.非常寬容的初學(xué)者。 The individual components to place are shown below.單個(gè)組件放置如下。 Its easiest with tweezers and some sort of magnification.其最簡(jiǎn)單的鑷子和一些放大排序。 A bit of patience and youll get it no problem.耐心一點(diǎn)，你就會(huì)得到它沒(méi)有問(wèn)題。 Since nothing gets soldered yet, you can easily try and try again if you mess up.由于沒(méi)有得到焊接，但你可以很容易地嘗試，再嘗試，如果你陷入困境。 R4, R5, R6, R11, R12 - 1.8K ohm resistor (182) 的R4，R5的是R6，R11的，R12的- 1.8K歐姆的電阻（182） This component can be placed in any orientation.該組件可以放置在任何方向。 R1, R13, R14, R18 - 10K ohm resistor (1002) R1和R13類型，R14的，R18的- 10K歐姆電阻（1002） This component can be placed in any orientation.該組件可以放置在任何方向。 R2, R3 - 1K ohm resistor (1001) 的R2R3 - 1K的歐姆電阻（1001） This component can be placed in any orientation.該組件可以放置在任何方向。 R7, R8, R9 - 3.3K ohm resistor (332) R7的，奧迪R8，R9的- 3.3K歐姆的電阻（332） This component can be placed in any orientation.該組件可以放置在任何方向。 R10, R15 - 4.7K ohm resistor (472) R10的，R15的- 4.7K歐姆的電阻（472） This component can be placed in any orientation.該組件可以放置在任何方向。 C3, C5, C8 - 100nF ceramic capacitor 補(bǔ)體C3，C5的C8的- 100nF的陶瓷電容器 These components can be placed in any orientation.這些組件可以放置在任何方向。 C1, C2 - 15pF ceramic capacitor C1和C2 - 15pF的陶瓷電容器 These components can be placed in any orientation.這些組件可以放置在任何方向。 Green and red LEDs 綠色和紅色發(fā)光二極管 These components can not be placed in any orientation!這些組件不能被放置在任何方向！ The red and green LEDs must be oriented correctly.紅色和綠色LED必須方向正確。 If you look very closely, youll see that one end of each led has small green stripes along the edges.如果你看上去很密切，你會(huì)看到一對(duì)LED兩端沿邊緣有小綠條紋。 Position the LED so that these stripes are facing in the same direction as the white dot on the silkscreen. LED的位置，使這些條紋是在同一方向上面臨著與白色的絲網(wǎng)印刷點(diǎn)。 Zoom in on the picture to make sure you get them right!在對(duì)圖片縮放，以確保您得到他們的權(quán)利！ IC1 - SN75176A IC1的- SN75176A This is the RS485 communications chip.這是RS485通信芯片。 It must be placed in the proper orientation.它必須被放置在正確的方向。 Place the chip so that the line across one end of the chip matches up with the heavy line on the silkscreen.放置芯片，使芯片在一個(gè)與端線匹配上的絲網(wǎng)印刷粗線。 It should face the bottom of the board.它應(yīng)該面對(duì)董事會(huì)底部。 C6 - 10uF electrolytic capacitor 的C6 - 10uF的電解電容 This component must be placed in the correct orientation .該組件必須放置在正確的方向 。 The black stripe on the capacitor should match up with the stripe on the silkscreen.電容器上的黑色條紋應(yīng)配合與絲印上的條紋。 Check the illustration to make sure youve got it right.檢查說(shuō)明，以確保您已經(jīng)得到它的權(quán)利。 SD Card Socket SD卡插口 This one is really easy, and you can place it with your fingers even.這一個(gè)是很容易，你可以把你的手指甚至用它。 If you look on the bottom of the SD card socket, youll see two little nubs or bosses that fit into corresponding holes on the PCB.如果你的SD卡插槽的底部，你會(huì)看到兩個(gè)小南京大學(xué)商學(xué)院或老板是到PCB上相應(yīng)的孔配合。 When you line them up and place the SD card socket on the board, these will make sure that it goes in exactly the right spot.當(dāng)你行起來(lái)，把主板上的SD卡插口，這將確保它在完全正確的位置去。 Nice.尼斯。 IC2 - Atmega644P TQFP IC2的- Atmega644P的TQFP This is the microcontroller that is the heart of the Sanguino.這是微控制器，它是心靈的Sanguino。 Before you put down the chip, smear away the solder paste a little- this helps reduce solder bridges.在你面前放下了芯片，涂抹掉焊膏一點(diǎn) - 這將有助于減少焊料的橋梁。 The small smooth circle on one corner of the chip lines up with the dot on the silkscreen.在一個(gè)小的芯片生產(chǎn)線一角順利圈與點(diǎn)上的絲網(wǎng)印刷。 Check the picture above to ensure that you have the chip in the correct orientation.檢查上面的圖片，以確保您有正確的方向芯片。 Make sure you get this right- if you solder the chip in the wrong orientation, it will be almost impossible to desolder it!確保你得到這個(gè)權(quán)利 - 如果你在錯(cuò)誤的焊接定位芯片，這將是幾乎不可能拆焊吧！ R16 - 180 ohm resistor (181) - OPTIONAL R16的- 180歐姆的電阻（181） -可選 This component is optional, so I would suggest you leave it out.這個(gè)組件是可選的，所以我建議你離開(kāi)它。 It is on the board in case you need it, and its in the wiki for completeness.它是在板的情況下，你需要它，它在維基的完整性的。 If you dont KNOW that you need it, leave it out.如果你不知道你需要它，離開(kāi)它。 TIf youre asking yourself right now Do I need this component? tif格式你現(xiàn)在問(wèn)自己“我需要這個(gè)組件？” the answer is no.答案是否定的。 This is a spot for a termination resistor on the RS485 bus and is generally not needed on most systems.這是一個(gè)RS485總線上的終端電阻點(diǎn)，一般不會(huì)在大多數(shù)系統(tǒng)需要。 Hot Plate Reflow 熱板回流焊 I prefer to start with the hotplate off.我更喜歡用電磁爐開(kāi)始了。 I burned a few boards one time by putting them on when it was already hot.我燒一時(shí)間把它們熱時(shí)，它已經(jīng)幾板。 Instead, carefully place the board on the cold hotplate, then turn the heat up to a low temperature.相反，小心地在冰冷的烤盤板，然后打開(kāi)加熱至低的溫度。 Wait a few minutes for things to get cooking, and youll see the small components begin to pop as the solder goes molten.等待事情，才能烹調(diào)幾分鐘，你會(huì)看到小零件開(kāi)始流行作為焊料去熔化。 Keep an eye out for components that stick together.隨時(shí)留意粘在一起的組件。 If that happens, simply nudge them apart with tweezers or other non-finger device.如果出現(xiàn)這種情況，只需輕推他們除了用鑷子或其他非手指裝置。 Wait until you see the largest component leads go silver (usually the big capacitors).等到你看到的最大組成部分線索去銀（通常是大電容）。 If it starts to smell really bad, kill the power and solder the rest by hand.如果它開(kāi)始真的不好聞，殺的權(quán)力和手工焊的其余部分。 Sometimes the capacitors wont fully solder, so just hit the exposed pad with a soldering iron after the fact.有時(shí)電容器不會(huì)完全無(wú)鉛焊料，所以只打一事后烙鐵裸露焊盤。 Once they have soldered, simply turn the hotplate off and let it cool down.一旦他們有焊接，只需把烤盤關(guān)閉，讓它冷卻下來(lái)。 For detailed instructions on how to do hotplate reflow soldering, please see the Hotplate Reflow Technique guide.如需查看詳細(xì)的說(shuō)明，關(guān)于如何做烤盤回流焊，請(qǐng)回流焊爐技術(shù)指導(dǎo)。 Clean up excess solder 清理多余的焊料 If you use the smear technique to apply the right amount of paste to the tiny TQFP parts, then youll end up with what looks like solder sand near the chip.如果您使用涂抹技術(shù)應(yīng)用糊適量的微小的TQFP零件，然后你就會(huì)像什么焊料與附近的芯片砂的樣子。 This is actually really easy to clean up.這實(shí)際上是很容易清理。 Simply take your hot solder iron and run it over the tiny beads of solder.只要把你的熱烙鐵和焊錫碾過(guò)它的小珠。 It will pick them right up and the board will be nice and clean.這將選擇他們的權(quán)利和董事會(huì)將非常干凈。 You may want to click through for a better view.您可能需要點(diǎn)擊一個(gè)更好的觀點(diǎn)通過(guò)。 Check for bridges! 檢查橋梁！ Before The fourth and fifth pins from the left are bridged.
