? Frequently Asked Question

How long does the test period take？

The normal period is 5-7 working days (except the time when the sample is in the test chamber). If you need urgent help, please contact our sales or customer service.

How much sample is needed for SIR （surface insulation resistance） and ECM （electrochemical migration）test of flux?

It is each recommended to send 200ml flux for SIR or ECM test.

what is the channel definition in ECM test?

In the process of ECM testing or SIR testing, To determine the number of test channels is to determine the number of positions of insulation resistance monitoring.

How long is the corrosion test exposure period of solder paste?

Different standards provide different test time. For example, GB/T 9491 recommends 7 or 14 days, while IPC J-STD-004B recommends 10 days, so the test time should be based on the standard specified by the customer.

How much solder paste sample is needed to test the wettability test?

It is recommended to send samples for more than 400g. If other test items need to be tested at the same time, it is advised to send more samples for standby use.
