AIM Solder, a leading global manufacturer of solder assembly materials for the electronics industry, is pleased to announce their participation in the upcoming SMTA Empire Expo taking place on September 27th at Rochester Institute of Technology, Rochester, NY. AIM will highlight V9, their new ultra-low-voiding, no clean paste, along with their full line of solder assembly materials.
Formulated to solve one of the industry’s most difficult challenges, V9 has proven to reduce voiding to as low as 1% on BGA and <5% on BTC components while exhibiting stable print performance on fine feature devices over 12 hours. V9 post-process residue is easily probed and possesses high SIR values required for high reliability applications.
To discover all of AIM’s products and services, visit the company at the SMTA Empire Expo on September 27th for more information and to speak with one of AIM’s knowledgeable staff members.

I recently spoke with Rob Boguski, president of Fremont, California-based Datest and an SMTA vice president and board member. Rob explained why today’s test customers are asking for more information than the traditional pass/fail, offers a preview of SMTA International, and gives an update on SMTA’s planning strategy for the next five years.

It may be difficult to see any bright spots in the current and recent economic situation. We have all experienced the devastation of the pandemic, supply chain issues, and most recently, inflation. However, as a senior technologist for an international materials supplier (Indium Corporation) and a professor of engineering at an Ivy League research university (Dartmouth College), I offer these four silver linings for those of us in the electronics industry.

The interdigitated back contact (IBC) is one of the methods to achieve rear contact solar cell interconnection. The contact and interconnection via rear side theoretically achieve higher efficiency by moving all the front contact grids to the rear side of the device. This results in all interconnection structures being located behind the cells, which brings two main advantages. First, there is no frontside shading of the cell by the interconnection ribbons, thus eliminating the need for trading off series resistance, losses for shading losses when using larger interconnection ribbons. Second, a more homogeneous looking frontside of the solar module enhances the aesthetics.
