  1. Choosing the right Surface Finish for Chip on Board assembly is crucial. One of the most frequent questions we are asked at KingCredie Technologies is how should my PCB be plated in order to ensure wire bond-ability. PCB Plating for Chip on Board Assembly must be planned in advance to ensure manufacturability of the device. This planning begins with design rules and selecting the wire bond method to be used. Common wire bond materials include aluminum or gold wire. Aluminum Wedge Wire Bonding and ENIG Plating One of the most common wire bond methods for COB assembly is aluminu
  2. Every digital clock has a crystal inside it to keep track of time. This crystal is not only present in the clock but also present in all computing real-time systems. This crystal generates clock pulses, which is needed for timing calculations. Although there are some other ways to get clock pulses for higher accuracy and frequency, but the most preferred way is to use crystal to keep track of time. Here we will DS3231 RTC IC to build an Atmega16 based Digital Wall Clock. DS3231 RTC has a highly accurate crystal inside it, so no external Crystal oscillator is needed. In this Digital Clock
  3. Well, here are several very interesting circuits : Remote Control Blocker by IR More than once we will have spent watching the best scene of a strip and that we change the channel. To avoid these little surprises that we do not like so much we have this powerful team that will be in charge of "flooding" with IR signal the enclosure avoiding that the remote control of the TV or the equipment that was working properly. The circuit is more than simple, the PNP transistor oscillates at the appropriate frequency of the equipment to be blocked while the NPN transistor amplifies the voltage to apply
  4. i make a PCB order at a China website www.allpcb.com/g6 and want to have them assembled for my project. but i was told it would take about 3 weeks, for pcb fabricating and assembly for only 50 units. i am wondering why it takes so long, is it normal?
