What is a component orientation indicators?
The Impression Block Orientation Indicator is an important component during operations where understanding the position of a fish within the tubing is critical. The Orientation Indicator can be fitted to an Impression Block and activation of the sub is simultaneous with the downward jar whilst obtaining an impression.
How components are mounted in the PCBs?
There are two methods of placing components on a printed circuit board (PCB). The first one is Through-Hole Mounting (THM) and the other one is specified as Surface Mount Technology (SMT). At EPR we use SMT as well as THM. Both methods have their advantages and disadvantages.
What is PCB assembly process?
PCB assembly process overview. The various stages in the PCB assembly process including adding solder paste to the board, pick and place of the components, soldering, inspection and test. All these processes are required, and need to be monitored to ensure that product of the highest quality is produced.
What should I know about component orientation on PCBs?
Marking orientation: Assuming that the component is oriented correctly to begin with, you can create a huge problem if your silkscreen marking is incorrect. Please make sure that your polarity indicators are marking the correct pins.
When to start documenting your PCB for assembly?
With your fabrication (bare board) requirements documented, it is now time to move on to an equally important stage — documenting the instructions for component placement and final assembly. It is in the assembly stage where your bare board is brought to life with all the components you specify in your Bill of Materials.
How are passive components aligned on a PCB?
Surface-mount passive components such as resistors, capacitors, and inductors, should be aligned perpendicular to the direction of the board going through the wave so that both pins get soldered equally. Larger SMT components should not precede smaller components through the wave.
How does rotation of parts on PCB affect manufacturability?
The rotation of parts on a PCB can have a great effect on its manufacturability, starting with the soldering process. For boards that are waved soldered, components that are misaligned could cause poor or bad solder joints, leading to intermittent electrical contact, no contact, or even direct shorts.
