SMD soldering tips

At one point or another, you will probably find yourself needing to solder a SMD (Surface Mount Device) package. Many people here might think SMD soldering is almost impossible. SMD soldering is usually a lot easier than it looks!

First you need right tools. The tweezers are very important in the entire SMD soldering process. Small diameter solder is a must (sometimes soldering paste is used instead traditional solder wire). You also need a suitable soldering iron. Depending what you do you need a very small or quite large soldering iron tip. You can start learning the skill with a normal temperature controlled soldering iron with a small tip.

The flux is very very important. Flux pen makes applying the flux very easy. Easiest is to use a flux type that you don’t necessarily need to wash off after soldering.

The solder-wick will help you clean solder off old pads, remove excess solder from solder joints, and remove solder bridges.

SMD Soldering Guide by Infidigm introduces SMD (Surface Mount Device) hand soldering. The guide is organized into different methods. A simplified list is included with each method to identify which types of SMD components are for the appropriate method.

Intro into SMD Soldering is a good tutorial on SMD soldering with example videos.

LOW COST SMD SOLDERING GUIDE article will take you through the process of soldering these surface mount parts, from simple two-pin parts to more complex TQFP.

    You’re right when you say that first you need the right tools. With so many variations of solder and different instruments to use in their application, it can be confusing for a new enthusiast. The white pages on http://www.indium.com were really helpful to me, and their resident scientist’s blog is a fun read: http://blogs.indium.com/blog/an-interview-with-the-professor

    Thank you for expressing these types of helpful details. Your article SMD soldering tips Tomi Engdahl’s ePanorama blog genuinely assists us a great deal. You should check our report likewise, should you not agree, also you can get away from your current remark.

    If You Give a Nerd a Microscope…

    Given the right tools — including a digital microscope — it’s possible for anyone who is reasonable adept to hand-solder electronic systems based on surface-mount technology (SMT).

    According to this ifixit column: “Jessa taught herself how to microsolder, fell in love with repairing electronics, and started a repair business called iPad Rehab in Mendon, New York. Now she does board-level repairs for a living and teaches microsoldering to other repair techs.”

    BGA Hand Soldering Video
    http://hackaday.com/2016/01/03/bga-hand-soldering-video/

    By 2016, most people have got the hang of doing SMD soldering in the garage–at least for standard packaging. Ball Grid Array or BGA, however, remains one of the more difficult packages to work with [Colin O’Flynn] has an excellent video (almost 30-minutes, including some parts that are sped up) that shows exactly how he does a board with BGA.

    [Colin] uses some spare boards to lock the target board down to his bench and then uses a custom stencil and solder paste to prep the board. Once he has the solder paste on, he places the components using a homebrew air tweezer and some regular tweezers.

    For reflow, [Colin] uses the common T-962A with the open source firmware. Two other modifications to the oven: a custom vent hood with a carbon filter and a Jolly Wrencher sticker for decoration (we heartily approve).
