The price increase of electronic components such as MLCC has not stopped. In recent years, driven by the development of electric vehicles, industrial control and other industries, the demand for MLCC products has increased rapidly. However, the overa

Thanks to @davef and @Evtimov for trying to help. It's useful but not exactly the answers I would like to get. I'm going to reformulate my question. I'm writing in mm so that it's more precise: I have a 0.12mm-thick stencil for some 0.4mm-pitch QFN

Sorry for switching accounts, the SMTA interface was not giving me the option to add attachments. Evtimor - IC testing of some samples of different assemble holes and components leads did not yield anything abnormal. SEM EDX of the unsoldered lea

There is a difference between VIOS and VIOS TEXT. If you want to copy the program from one machine to another exactly, I would suggest you do VIOS. Just insert a floppy and perform "Make PCB Data Disk". This formats the disk in VIOS format. Next go t

We have been having some issues recently with a TSOP-II 54 pin, where upon second reflow the part will lift at end one, most of the time the solder will pull up with it and still connect but I still worry about strain on the component as well as it i

In our reflow oven it has pins which move at the predetermined speed to move the pcb through the various zones in the oven. The forward row of pins is fixed along the front of the oven. The rear set of pins is adjustable per the width of the pcb. We

We have a printer with Hawkeye 1700. The PCB side sometimes returns a distorted picture. It happens erratically, can be at startup or after a while, sometimes the machine works full day without problems. The only way to restore operation is disconnec

We have an electrovert 16" econopak wave solder machine with two identical pots (exchange between Tin Lead and Lead Free). When the pots are exchanged the same thermocouple is used, and the same controller is used - with the set point adjusted. The S
