When it comes to unique circuit board modifications, why not turn to the pro and MacGyver it? All kidding aside, sometimes unusual modifications and component additions are necessary. Ever stack components or mount them upside down?
Here’s a modification that is on its way to becoming part of IPC documented guidelines.
Axial lead component soldered to through-hole component leads.
For more modifications, just follow these “tricks” of the trade. You can learn how to bend the rules and do it safely:
- Secure added components with adhesive if the component leads or body will undergo mechanical stress.
- Consider placing components end-to-end where applicable.
- Place added components on the component side of the assembly or circuit board unless otherwise specified.
- Consider insulation for added component leads that may come into contact with component body or other conductors.
- Remove existing solder in the connection to avoid bridging or excess solder in the final connection.

Recent U.S. tin prices have made it an opportune time to buy solder wire in bulk, especially for major production and electronics manufacturing environments.
Solder manufacturers such as Alpha–known for its advanced solder wire technology–adjust their prices throughout the year based on the fluctuation of tin costs.
Currently, the price of tin per pound is at its lowest point since 2010. And while demand may be in decline and customers appreciate the lowered costs, it may be unlikely to last–similar to the recent, lowered gas prices.
Yet, at the moment, Alpha distributors and customers alike are able to take advantage of this temporary decline in the cost of tin.
Overall tin prices have climbed significantly since the early 2000s, when the average pound was approximately $2. During 2011, it reached a peak of nearly $15. And since late 2013, the price has steadily declined from approximately $11 to where it stands today at $8.
The low costs of Alpha solder wire at All-Spec is just one example of the effect of tin price on solder wire.
