Evaluating Performance for Adjustable Soldering Systems

By Curtis Yamauchi on May 15, 2020 6:17:02 PM

When looking at performance for hand soldering in electronics manufacturing, Operations Engineers need to be very focused on three key metrics: time to temperature, dwell time and thermal recovery. These three metrics together will identify the best soldering product for the production line and will help maximize throughput and lower scrap in the process.

Removing Solder and Adhesive without Damaging PCB Component Pads!

By Metcal Marketing on Jul 26, 2017 9:48:11 AM

If you have a bunch of complicated boards that need rework, and you need to remove solder and adhesive, it's a time consuming and risky application. In fact, even the most experienced and technical operators can get into delicate situations when faced with repeating component and pad cleaning over and over.

Rework Challenges for Leading Edge Components BGA, QFN and LED in Today’s Fast Moving Industry

(see also below: Risk Mitigation in Hand Soldering)

Presented by Paul Wood, Metcal Advanced Product Applications Manager                                        

The electronics assembly industry continues to face the challenges associated with BGA, QFN, and LED packages. The demand for more performance by consumers drives change, which results in greater component density. Component density on printed circuit boards continues to decrease with a corresponding increase in component complexity and reduction in pitches. Good examples of these industrial trends are smart phones, tablets and wearables.

Industry Trends Making Manual PCB Cleaning Increasingly More Challenging

By Metcal Marketing on Oct 27, 2016 1:30:07 PM

In addition to PCBs becoming thicker over the years, pad and pitch size have also reduced significantly, with many smartphones and other devices now utilizing pad sizes as small as .25mm millimeters spaced at intervals of .5mm. It is known in the industry that new chips are scheduled for release in the next two to three years that utilize designs calling for pad sizes as small as .15 mm with a .3 mm pitch. With adjacent parts so close together, avoiding hitting them with the wick during manual cleaning—and creating another round of rework—will most likely become impossible for even the most skilled technician.

Further, traditional cleaning methods can be even less effective when it comes to cleaning PCBs incorporating advanced chip technologies. For example, one new technology is providing outstanding improvements in security, making it nearly impossible for criminals to access data stored on the processor. However, due to factors such as differing size pads and uneven solder volumes, manual cleaning can be a significant challenge. 


Another technology, Ceramic Ball Grid Array (CBGA), a specialty process used in aerospace, military and other high reliability applications, is another high value case in point. These boards,

Contactless solder cleaning is rapidly replacing manual cleaning in more and more PCB rework applications

By Metcal Marketing on Oct 18, 2016 5:44:37 PM

Today's manufacturers of printed circuit boards (PCBs) are strongly quality driven, but even among those operations that are able to drive yields near or even above 99%, the huge volumes associated with applications such as smartphones and tablets could still leave them with thousands of boards per week that come off the assembly line damaged and in need of rework.


Since the cost of these PCBs can be well over US$200 each, most manufacturers and OEMs consider it vital to develop an effective process for working to reclaim these boards and minimize scrap PCBs—and the resulting losses—in their operations.
