All that’s required to measure radiation is a simple PIN photodiode and a suitable preamplifier circuit. We present here an optimised preamplifier and a microcontroller-based counter. The microcontroller takes care of measuring time and pulse rate, displaying the result in counts per minute.The device we describe can be used with different sensors to measure gamma and alpha radiation. It is particularly suitable for long-term measurements and for examining weakly radioactive samples.

Mitsubishi Electric has developed a thermal sensor able to accurately distinguishes between humans and other heat sources, for the identification of specific human behaviour, such as walking, running or raising hands. by Julien Happich @ www.eenewseurope.com
Designed with a high pixel count (80×32 pixels) for security and smart building applications, the Mitsubishi Electric Diode InfraRed sensor (MelDIR) relies on thermal diode infrared sensor technology the company developed for the Advanced Land Observing Satellite-2 “DAICHI-2” (ALOS-2).
Compared to today’s 16×16 pixel thermopile sensors, the device offers 10 times higher pixel resolution and five times higher thermal resolution at 100mK, or 0.1 degree Celsius. Each thermal diode (or sensor pixel) is supported by microfabricated legs that convey energy efficiently without releasing heat, enabling more pixels to be used for increased resolution.
Electrical noise is minimized by mounting the thermal diodes and high-spec amplifiers close to each other on the same chip, helping to maintain accuracy and achieve high thermal resolution. The detailed infrared images make it possible to distinguish between humans and other heat sources as well as to identify specific behaviour.
Measuring 19.5×13.5×9.5mm, the device comes in a package 80 percent smaller than that of existing sensors, it boasts a 78º x 29º field of view and has a detectable temperature range of -5 to +60ºC. Mitsubishi Electric used a proprietary chip-scale packaging and vacuum-sealing technology to ensure the sensor is vacuum sealed (without using conventional ceramic package) to avoid heat radiation and achieve high thermal resolution.

Today we are going to share with you a real case study involving a Seeed Fusion PCBA customer’s design. At the time of placing the order, the customer requested the default HASL surface finish, but listed in their Bill of Materials was a 0.4mm BGA. It’s a small BGA with only four balls in the array, but the combination of 0.4mm pitch BGA and HASL surface finish should ring alarm bells, and here’s why:

LCSC.com logo
A quick search of “Arduino Uno” doesn’t return any results making it seems the site isn’t meant for the complete newbies or those looking for hobby only parts. Having used Digilent or Mouser for parts purchases in the past, I must say that the two sites share some similar resemblance, especially in the ways the products are being displayed and filtered. It seems that LCSC builds their website with the customer in mind and for easy navigation.
International shipping is supported through several third-party agencies, and PayPal payment is possible as well as other credit-card based payment.
LCSC.com also purchased EasyEDA back in 2017, the online easy and powerful to use PCB design tool to offer streamlined design services for PCB users using the EasyEDA platform.
