EPR optimises PCB rework with Kurtz Ersa HR 550 and training

Case study

EPR, a leading EMS provider in the Netherlands, supplies high-quality electronics that are fully tailored to customer-specific requirements. However, the sector in which EPR operates faces challenges such as increasing product complexity and the demand for more flexibility in assembly processes.

To completely unburden its customers, EPR decided to make a strategic investment in the HR 550 Rework Station by Kurtz Ersa. This powerful hybrid rework system is ideal for demanding applications in the electronics industry.

Kurtz Ersa HR 550 – a powerful hybrid rework system

  • Hybrid Heating: A 1,500 W upper hybrid heating element and a 2,400 W infrared bottom heater with three heating zones ensure even heating, ideal for soldering and desoldering tasks.
  • Precision: Computer-guided component alignment using HD cameras and integrated force and temperature sensors guarantee a precise rework process.
  • Versatile: Suitable for a wide range of component sizes, from 1 mm² to 70 x 70 mm, including BGAs and THT components

In addition to the technological upgrade, EPR invested in its employees by having them follow the BGA Rework & Repair training at Smans. They learned how to carry out complex rework assignments according to standardised methods.

Knowledge about this process is essential to achieve higher efficiency and quality. For example, the difference between gel flux and classic flux is an eye-opener Did you know that gel flux is used to (re)attach components and classic flux is used to remove components?

Gel flux: thick liquid

Classic flux: thin liquid
When (re)attaching components When removing components
Stays in place From wave & selective soldering
Adhesive strength No adhesive strength
Long-term heat resistance Shorter-term heat resistance

Capillary action under components (BGA)

 

The combination of HR 550 and the knowledge gained offers EPR considerable advantages. The company can now offer a streamlined rework process, with less time lost and improved output quality.
