PCB Drill entry&backup board
Prceise enginned PCB Drilling Material For PCB excellence!
A stable and cost-effective backup material for PCB and FPC drilling. It supports the PCB panel during drilling, reduces exit burrs and helps protect the drilling machine surface.
UV coating backup board
exceptional surface smoothness- dimensional stability optimal resin flow control – minimizes burr formation – extends drill bit life – HDI, multilayer, fine-pitch applications
Alu entry board
A precision entry material placed on top of PCB panels to improve drill bit positioning, heat dissipation and hole accuracy in high-speed or micro-hole drilling.
strictly quality control
Quality Control Measures on PCB Backup Boards
Use high-quality substrates with good thermal stability and uniform thickness to prevent warping and stress concentrations.
Implement symmetrical designs and balanced copper distribution to ensure even stress distribution and minimize warping.
Maintain consistent temperatures and manage humidity in production to prevent thermal stress and moisture absorption
Conduct thorough visual inspections and dimensional checks to identify defects and ensure compliance with specifications
Store boards flat and avoid stacking; train staff on proper handling techniques to reduce physical stress
Implement standard operating procedures for consistency and establish feedback mechanisms for continuous improvement.
