BGA Conductor Receives a Path Redesign

Posted on by Michelle R. in Technical Articles Leave a comment

From design to production, circuit boards require hours of planning, execution, revision and more revision to arrive at a final product (until the next model comes out). Recently, BGA conductors were evaluated and found to have a design that contained a flaw involving 23 of the 676 balls on their component. The problem? They weren’t connected where they needed to be connected.

With re-routing as the only viable solution, the design team set about what was a major undertaking. Had the pads that required re-routing been located on the perimeter of the BGA’s layout, the rework would have been much easier. However, their actual location proved to be a challenge that would require meticulous planning.

It was decided that the newly routed pads needed to extend from the center of the component, and they would stretch to the outside of the package footprint so wires could be added to the newly designed pattern of the surface mount pads.

Easy in theory. A bit more challenging in practice.

The initial design placed the new circuits too close to those on the circuit board. Creating a configuration that prevented the newly laid circuit from interfering with the solder paste stenciling and BGA placement required several intricate operations before the new paths were placed where they needed to be.

Lead-Free Solder: What You Need to Know

Posted on by Michelle R. in Technical Articles Leave a comment

Health dangers associated with lead use are well-documented, and most countries have already begun the transition to lead-free soldering solutions because of these negative effects. Here’s what you need to know about working with lead-free solder.

Advances in soldering chemistry are slowly allowing lead-free solder to shed its reputation as an inferior alternative to lead-based solder. Adding tin, silver, copper and nickel in various amounts adds strength to lead-free solder and, in some cases, offers superior strength.

Lead-free solder also has less impact on the environment when used over the long term, as properly disposing of lead presents its own unique set of challenges. Lead-free alternatives are easier to dispose of when no longer needed, and they pose a much smaller risk to health.

It is important to note that the more pure lead-free solder is, the stronger and more reliable it is. This means that you should never mix it with lead-based solder, as this can lead to weakened joints. Also, lead-free solder does not require special soldering irons for use, especially when the application calls for switching soldering material.

The Care and Keeping of Your Hakko Soldering Iron

Posted on by Kathy S. in Soldering Tips and Tricks Leave a comment

The Care and Keeping of Your Hakko Soldering IronYour shiny, new soldering iron tips won’t stay that way for long. But, with proper maintenance, you can help ensure the quality results you expect from your quality iron. Hakko recommends five do’s and don’ts for lower melt times, cleaner solders and a longer iron life.

  1. Don’t reshape your soldering iron tip.

Filing or grinding the tip can cause permanent damage. Instead, buy replacement tips in the different shapes and sizes you need; it’s much more economical in the long run.

  1. Do tin your tip.

With each use, and after any long pauses, be sure to add a fresh dollop of solder to the tip in order to tin it. This helps to remove any leftover oxide. Tip tinners and cleaners that are a mixture of solder paste and flux can also be used to help remove oxides.

  1. Do clean your tip.

You do need to clean your tip frequently, and if you need to take a break longer than an hour, or you are working at temperatures above 665◦F, you’ll need to clean the tip before you resume soldering.

  1. Do use a proper sponge.

When you clean your tip, use a damp, synthetic sponge—no rags or fabrics.

  1. Don’t use tap water.

Tap water may contain contaminants and should be avoided. Do dip your sponge in distilled water before cleaning the tip of your soldering iron.

Following a few simple steps can extend the life of your soldering iron to its maximum and keep your tips gleaming in the process.
