Nicolas Garcin, electronic engineer at ALTYOR, gives us his 8 top tips for understanding the importance of test benches, a vital stage in the industrialization of electronic products.
#1 – A step not to be overlooked
A test bench is a piece of equipment used to check products after they leave production and to ensure that they comply with specifications. These tests could be carried out manually, but automating them means that they are secure and standardized.
At ALTYOR, 100% of our circuit boards are tested during the production phase. A PCBA (Printed Circuit Board Assembly) can perform differently depending on the components and the battery it contains. The tests are therefore there to ensure consistency and guarantee that the products you purchase are faultless.
#2 – Two test benches for maximum reliability
There are two types of test benches for testing electronics:
- Pre-assembly test benches to test circuit boards, particularly the sensors positioned on them prior to final assembly
- Assembled test benches to test the electronic functionalities of finished products
#3 – Software/Firmware and mechanics
Test benches consist of two components:
- Software: developed specifically for the product, this software is responsible for linking the test scenarios connected to the firmware and the circuit board, driven by the test bench.
- A bed of nails (mechanical component): also specific to each product, this consists of several metal pins that touch the contact points on the circuit board.
