Prama Hikvision India Interview Questions, Process, and Tips

Yes, I perform preventive maintenance activities regularly to ensure smooth functioning of SMT and THT machines.

• Perform regular inspections and cleaning of machines

• Replace worn out parts before they cause breakdowns

• Keep a record of maintenance activities

• Schedule maintenance during non-production hours

• Train other technicians on preventive maintenance practices

MTTR means mean time to repair and MTBF means mean time between failure.

• MTTR is the average time taken to repair a failed component or system.

• MTBF is the average time between two consecutive failures of a component or system.

• Both MTTR and MTBF are important metrics in maintenance management.

THT stands for Through Hole Technology, which involves inserting leads of electronic components through holes on a PCB.

• THT is a traditional method of mounting electronic components on a PCB.

• It involves drilling holes on the PCB and inserting leads of components through them.

• The leads are then soldered on the opposite side of the PCB to make a connection.

• THT is commonly used for components that require high mechanical s...read more

We are using Electrovert Wave solder machine with five preheaters.

• We use Electrovert Wave solder machine for SMT and THT maintenance.

• The machine has five preheaters.

• The preheaters help in preparing the PCB for the soldering process.

• The preheaters ensure that the PCB is at the right temperature before it enters the wave solder machine.

• This helps in achieving better soldering results and reduces the risk of defects.

We are using G-tech router for depanelling in THT department.

• G-tech router is a type of depanelling machine used in THT department.

• It is used to separate individual PCBs from a panel.

• The router uses a high-speed spindle to cut through the board along the designated routing path.

• This process is faster and more precise than manual depanelling.

• G-tech router is commonly used in electronics manufacturing industry.

Spindle motor is used in G-tech router.

• G-tech router uses spindle motor for its operation.

• Spindle motor is a type of motor used for rotating the cutting tool in the router.

• Spindle motor is designed to provide high speed and precision.

• Examples of spindle motors used in G-tech router are air-cooled spindle motor and water-cooled spindle motor.

Yes, I am proficient in creating new programs for G-tech router.

• I have experience in using G-tech software and programming language.

• I am familiar with the router's hardware and software components.

• I can analyze and interpret technical drawings and specifications.

• I have created programs for various types of G-tech routers, including the XYZ model.

• I can troubleshoot and debug programs to ensure optimal performance.

SMT stands for Surface Mount Technology, a method of electronic component assembly.

• SMT involves mounting electronic components directly onto the surface of a printed circuit board (PCB).

• This is in contrast to through-hole technology (THT), where components are inserted into holes drilled into the PCB.

• SMT components are typically smaller and lighter than THT components, allowing for higher component density on a PCB.

• SMT...read more

Yes, I am familiar with nozzle calibration and maintenance.

• Nozzle calibration involves ensuring the nozzle is properly aligned and adjusted to the correct height for optimal performance.

• Nozzle maintenance includes regular cleaning and inspection to prevent clogs and damage.

• I have experience with both SMT and THT nozzle calibration and maintenance.

• Examples of maintenance tasks include checking for wear and tear, replaci...read more

Yes, I am familiar with feeder maintenance and calibration.

• I have experience in cleaning and inspecting feeders regularly to ensure proper functioning.

• I am skilled in calibrating feeders to ensure accurate placement of components.

• I am familiar with troubleshooting feeder issues and replacing faulty parts.

• I have worked with both SMT and THT feeders.

• I understand the importance of maintaining accurate feeder records for e

Yes, I am familiar with changeover and programming of Peak and place, SPI, and solder paste printer machines.

• I have experience in setting up and programming these machines for efficient production.

• I am knowledgeable in troubleshooting and maintenance of these machines.

• For example, I have successfully programmed a SPI machine to detect and correct solder paste defects.
