Struggling planning your analyzer?
Planning and conceptualizing an ATE is anything but a simple assignment.
Here are a few focuses and steps you may consider in planning your own computerized test gear (ATE) that will meet your requirements.
Rundown down all the current force supply, recently foster force supply and the future tasks with the accompanying required data:
o Input Power necessity: for input source, you need to arrange for what info source you may have to cover all information prerequisite for all the your product offerings.
o Output power prerequisite: number of burdens you need to consider, this will go from the powerful reach to low power range.
o Number of yields and signals: this is basic since you need to get ready for the standard mux assignment. For this, more mux distribution the better.
o Control switches: audit each test necessity for every one of the item for all the test that requires transfer or switches. You must be cautious in arranging this out. This will be use on the number of broadly useful switches or transfer you will introduce in your ATE. You can check additionally new test philosophy that may be conceivable test for the new items.
From the rundown, you ought to achieve the accompanying data:
o You will have a thought on what info source led dimming driver your going to use to cover all force supply you’re going to test.
o You will have a thought on the number of burden modules you need to introduce to cover high force various yields power supplies. You will likewise have to add low current burden module for lower current yields.
o You will have thought on the number of muxes and changes your going to utilize.
Test Interface Panel
You need to consider the test interface your going to use for your ATE. There are a ton of decisions on the lookout.
For test board connector, you need to think about the accompanying:
o Quality of contacts, great contact tests to dispose of contact obstruction that will influence your estimations.
o Flexibility, simple to connect, simple to unplug, fast separate, low inclusion and extraction power required.
o Serviceability, simple to supplant. You need to think about likewise on the connector that is not difficult to supplant and
o Contact life cycle, you need to consider long life cycle connector else you need to transform it often.
You need to think about the accompanying focuses for choosing a gear.
o Availability of hardware – ensure that you will have a lasting gear for your ATE.
Since the hardware will be fixed on your ATE, ensure that the gear won’t be imparted to other test arrangement.
o Communication interface of the hardware, typically all gear have GPIB (broadly useful interface transport) for controller.
o You need to consider likewise that in building ATE, this will be a standard test arrangement. You may assemble more ATE utilizing same setup from hardware to programming. In such manner, you need to consider a hardware that still accessible in the market simply in the event that you need to assemble more ATE.
o Serviceability, consider a gear that specialized help from the producer is as yet accessible.
o Easy to introduce on your ATE Rack, typically, test gear are in standard sizes, generally its 19″ wide which will fit on the 19″ rack.
Utilize fitting links for your ATE.
o Load Cables: utilize evaluated links that can deal with appraised greatest current of every module. Ensure that you need to consider just 80% of the link ampacity.
o Sense link for voltage detecting to you DVM: utilize a wound abandoned wire for your detecting to your DVM.
o Sense link for the Oscilloscope: utilize protected persuade link, scope tests.
o Input links for input:
For AC, Make sure that you will check the evaluated ampacity of the link. Ensure that the ground is associated too. Utilize wound abandoned slim link for the sense.
