Quality Products backed by The Weller Way


All Electronics and Mechatronics cores are disassembled by skilled techs who then inspect every part to be reused. Soft parts and consumables are discarded. Hardware and castings are cleaned and reconditioned. Printed circuit boards are stripped and washed. All recovered parts are final inspected before send off to assembly.


Parts to be remanufactured then flow into our purpose-built Electronics and Mechatronics lab. The lab is climate controlled and outfitted with industry standard electro-static discharge mitigation systems to ensure quality. All products are remanufactured with mandatory component replacement lists of up to 65 individual, board level components. These parts often include EEPROM, processors, drivers, and RAM.

As standard policy, all circuit board rework is performed to IPC 7711/7721 standards by certified technicians.   


Every Weller Remanufactured Electronic or Mechatronic part is subjected to multiple tests after reman, to ensure quality. Our testers are purpose built by us, and simulate operation of the part while in dynamic operation. All parts are tested at least twice, once at ambient and once at an elevated temperature similar to real word operational conditions. Some products have known failures such as in sub zero temperatures or under vibration, Weller has taken this into account with environmental testing from -20* to +230*C and up to 500 G-force.
