The $399 Mavic Mini lives in a sweet spot of core features and a low price. It packs everything critical to be a quality drone. It has a good camera, good range and a good controller. It holds up well in the wind and is quick enough to be fun. And it’s so small that you’re more likely to throw it in your bag and take it on Instagram adventures. The small size is the Mavic Mini’s main selling point. It weighs 249 grams, and that odd number isn’t an accident. Drones that weight 250 grams and above have to be registered to fly.

Most come loaded with countless feature...

Agfa on Revolutionary Inkjet Solder Mask Applications

Does inkjet solder mask have the potential for volume production? Mariana Van Dam, global sales manager for PCB imaging solutions, and Dr. Frank Louwet, business unit manager for advanced coatings and chemicals, discuss Agfa’s latest developments, plus some novel applications for inkjet etch and plating resists. Pete Starkey: I’m at electronica 2018 with Agfa, and am delighted to have the opportunity to sit down with Mariana Van Dam and Frank Louwet to talk about developments in inkjet resists. It’s lovely to meet you both again. We seem to catch up with you at most of the major events, and we’re very interested to hear about the progress of your product developments, particularly in inkjet solder mask. In my previous experience, it appeared that inkjettable solder mask was an unachievable objective, but you seem to have made it into a reality. Can you bring us up to date with recent developments in the formulation, qualification, and customer acceptance? Frank Louwet: Yes. We have focused on the green-coloured solder mask for rigid PCBs. The inkjet solder mask development in Agfa started about two or three years ago. During our interview last year at productr...
