A Look at Our Readers’ Manufacturing Challenges


Reading time ( words)

In a recent SMT007 survey, we asked the following question: "What are your greatest challenges when it comes to soldering?" Here are just a few of the replies, slightly edited for clarity.

Jon Ashton, Vergent Products: Selective soldering is not covered (as a process) by any specific IPC/J-STD document that I can find. The training, even from our equipment supplier, is prohibitively expensive. That makes improving the process harder than it should be. Regarding SMT PCBA design, there is a lot of bad data out there in existing CAD/CAM libraries, and the manufacturer’s datasheets are often the source of this bad information.

Jeff Vaessen, Borg Indak: Choosing the right tip geometry is the biggest challenge for any solderer. The right tip makes all the difference in the world.

Pongtip Pattarateerawat, Celestica Thailand: The wave soldering process is more challenging than the SMT reflow process, as there are a variety of PCB design and component considerations when it comes to wave soldering.

Yingyos Sookchai, SVI Public Co. Ltd: Achieving solder fillets with perfect wetting and avoiding damages to components.

Tips & Tricks: Water Contamination and Flux Expiry

04/17/2019 | Jason Fullerton, MacDermid Alpha Electronics Solutions
Solder joints that form properly are not expected to exhibit reduced reliability. However, a higher number of defects created tends to lead to a higher chance that defective connections escape detection through inspection and functional testing, and that’s not a risk to be taken lightly.

Tips & Tricks: Humidity Level for Electronics Assembly

04/10/2019 | Jason Fullerton, MacDermid Alpha Electronics Solutions
Low relative humidity (RH) can allow for higher static charges to build on objects. It can also affect solder pastes, especially OR-class pastes, and this can reduce print performance and stencil life. Read on to find out what level of RH you need for your assembly facility.

IPC Working to Revive Lead-Free R&D in High-Reliability Sectors

04/10/2019 | Chris Mitchell, IPC VP, Global Government Relations
Ask yourself the following question: Why is it that the aerospace, defense and high performance (ADHP) electronics sectors remain reliant on lead solders and components even as the commercial sector has largely phased out their use?
