In electronics manufacturing, the precision of PCBA (Printed Circuit Board Assembly) mounting directly affects product reliability, service life and brand reputation.
With the explosive growth of 5G, new-energy vehicles, medical electronics and other high-end applications, traditional assembly tools can no longer satisfy the “micron-level accuracy + zero-defect” requirement.
A single oversight—e.g., a screw dropping onto the PCB or conductive dust settling on the surface—can cause a short circuit.
Once the board is electrically punctured, the entire PCB or even the whole electronic control enclosure must be scrapped, wasting material and stopping the line.

Pain Point 1

Conductive dust (metal chips, etc.) clinging to screws or introduced during feeding can fall onto the board and become a short-circuit hazard.

Danikor solution

Step-feed screw feeder + multi-stage cleaning modules:

1. Hopper: vibration-free design with built-in dust collection box and vacuum port removes residual particles at the very first step.

2. Track section: individual screws are blown/vacuumed while moving along the rail.

3. Blow-and-vacuum module: after singulation, the screw is blown toward the nose; an independent vacuum nozzle performs a second dust removal.

4. Nose unit: grips the threaded portion, then the cylinder lowers to the vacuum pick-up position. Vacuum is switched on to suck away tapping debris and bit-to-head metallic dust.

5. Only after vacuum confirmation do the gripper jaws open; the suction tube descends, places the screw at the target hole and tightening begins.
   The result is a visibly cleaner screw and a greatly reduced risk of particle-induced shorts.

Pain Point 2

Electro-static discharge (ESD) from operators, tools or equipment can puncture delicate components on the PCBA.

Danikor solution
Intelligent screwdriver housings are moulded from anti-static engineering plastic and contain an internal ground wire.
Ground impedance < 10 Ω safely drains any static charge from the tool surface, preventing ESD damage to sensitive devices.

Pain Point 3

Missing, wrong-sequence or dropped screws can cause loose joints or short circuits, degrading overall quality.

Danikor solution
Graphic-guided software + smart screwdriver + torque arm form an integrated error-proofing package:

• Scan the product barcode to activate the correct work instruction.

• On-screen graphics show the operator the exact sequence and position.

• If the bit is not at the pre-programmed coordinate, the tool remains locked; only when the correct hole is reached is tightening enabled.

• The smart driver continuously monitors torque and angle, automatically detecting floating threads, cam-outs or cross-threads in real time.

Together these measures eliminate wrong-order or missed screws and guarantee every joint is correctly tightened.

By addressing dust, ESD and human error in one coherent platform, Danikor helps electronics manufacturers reach true “zero-defect” PCBA assembly while keeping line throughput high.
