New firmware v.24 released

JandM Retro Chip Tester

New firmware release (v.24) after six beta versions!

There are many minor and major improvements, such as
– a simple clock generator (300 Hz to 8 MHz in 46 steps)
– the identification of unknown logic ICs
– improved support for exotic SRAMs, such as the EMM4200
– a lot of “new” logic ICs have been added

There is also a new adapter for the rather exotic DRAMs Motorola MCM6605
and Intersil IM7505A (the Gerber files have already been released).

ENIG (Electroless Nickel Immersion Gold) surface finish is coming soon!

JandM Retro Chip Tester

We have exciting news to share: ENIG surface finish is coming soon as a standard for RTC Pro PCB

ENIG is quickly becoming the most popular surface finish in the industry. It’s a double layer metallic coating, with nickel acting as both a barrier to the copper and a surface to which components are soldered. A layer of gold protects the nickel during storage. ENIG is an answer to major industry trends such as lead-free requirements and rise of complex surface components (especially BGAs and flip chips), which require flat surfaces. But ENIG can be expensive, and at times can result in what is commonly known as “black pad syndrome,” a buildup of phosphorous between the gold and nickel layers that can result in fractured surfaces and faulty connections.
