HOW DOES LEAD-FREE SOLDER DIFFER FROM REGULAR SOLDER?
With the global electronics manufacturing industry moving swiftly towards sustainable production and environmentally safe practices, the demand for eco-friendly raw materials has increased exponentially. The biggest development in the field came with the RoHS directive that urged manufacturers to move towards safer manufacturing materials. That is how lead-free solder gained popularity. This article will provide you with key information on the characteristics that differentiate lead-free, rosin-core solder from the regular solder.Bonding temperaturesThe most prominent difference between lead...

Lead-Bearing Solder Paste Applications
Solder paste is necessary in the manufacturing of PCBs (printed circuit boards), as it is used to connect the surface mount components to the pads on the PCB. It acts like an adhesive or a glue that ensures surface mount parts are secure on the board. Besides holding the PCB components in place, a good solder paste also ensures an excellent electronic bond between the PCB and its components. Hence, it is typically formulated with conductive materials, like lead and tin. Solder paste is basically powdered metal which usually comes suspended in flux. The paste consistency of the solder serves as...

Uses of Stencils in Electronics
The term stencil might remind you of your childhood days of crafting beautiful drawings with colorful cutouts of plastic that would serve as a guide to create perfect shapes. With the advent of electronics engineering, the funny world of stencils is now industrialized, and has become highly technical. By definition, stencils are just a thin sheet of plastic or Mylar with some tiny holes cut out in it. They are used in electrical engineering for various applications. Let’s see some of the uses and advantages of stencils in electronics and fabrication of circuit boards.Advantages of stenci...

Things to Know About Using Lead-Free Solder Paste
Solder typically contains lead but, due to safety concerns, manufacturers of electronic products and devices are switching to lead-free solder pastes. Certain applications may require lead-free solder paste for PCB assembly in handheld electronic devices (i.e. tablets and smartphones), consumer electronics, automotive systems, military and medical equipment, network servers, and computer motherboards. Lead-free solder paste must be properly formulated to ensure high throughput and reliability for the intended application. Following are some of the most important things to keep in mind while se...

Solder Alloys?How to Select the Best Option for Your PCB Assembly
Not all solders are created equal. Each alloy type has a specific temperature specification and is suited to a specific set of applications. Choosing the right solder alloy can make or break your PCB assembly, affecting the reliability, accuracy and performance of the circuit board being manufactured as well as the cost effectiveness of your overall operations. Therefore, as a PCB manufacturer, it is important that you carefully analyze different solder alloys and select the one that perfectly fits your requirements. To help you with the selection, here is a guide that talks about all the fact...

Solder Balls and their Negative Effect on the PCB Assembly Process
If you are a PCB manufacturer, the word ‘solder balls’ must be extremely familiar to you. In fact, you have likely marked the phenomenon of solder ball formation as one of the greatest challenges of your SMT reflow process. The issue is fairly common and can be caused by a host of different factors, mainly poor process conditions, and can genuinely compromise the electrical reliability of the assembled printed circuit board. This article presents a comprehensive overview of the solder ball defect along with an insight into possible causes of the same and also lists out recommended ...

Know About the Process of Solder Dross
The soldering process requires the use of a high-quality solder to ensure that components can stick together and create an efficient bond that will enable electrical current to pass. However, it can involve the production of dross, which naturally develops due to exposure to oxygen. Dross is typically created when solder goes back from the nozzle to the solder pot when it mixes with the air around it to oxidize. The result is waste material that is typically a combination of used flux and oxidized solder alloy. Dross usually settles over the solder when lead-based alloys are involved, and this...
