We recently made a few tutorial video on how to use the HWGC HW-T4-50F pick and place machine and they are made available for viewing on YouTube. We love our pick and place machine very much but we also at the same time wished it had more detailed documentation and manual. After more than a year of using the machine, we got pretty familiar with the machine’s in and out. We felt that the machine in overall is an excellent piece of investment. We started to make boards way much faster and spent so much less time on manufacturing. The machine software is quite intuitive but has it’s own quirks and some untranslated parts. We are not going to talk a lot on this post but will allow the videos do the talking. We hope you guys find the videos helpful and if you like them, please give them a big thumbs up! If time permits, we will add a few more videos on the machine like camera & nozzle calibration and footprint library.

Take care!

Here at Rocket Scream, every boards are tested before being put on sale. When we first started, we have to admit we were awfully ineffective in testing each product that we made.

When we first started Rocket Scream Electronics about a year ago, we were in dilemma on which CAD package to use. This is simply because we were using Altium Designer while we still have access to them back then. It is a very efficient and easy to use CAD package despite it’s complexity and monstrous look. Secondly, being a tiny start up company, we simply could not afford to purchase Altium Designer even though they lowered down their price (they used to cost like a piece of car!). So, we embarked on a journey to get ourselves an affordable CAD package with the feature we were looking for. Read more




With so many off the shelf radio modules available in the market, designers would probably being swarmed by all kinds of technical jargons and numbers like frequency modulation, receiver sensitivity, maximum output power, data rate, networking topology, channel capacity, addressing mechanism, and the list goes on and on.
