30 HP variable frequency drives are available online as well as at store. One can buy them online or from the store for their motor which will support 22kw or higher variable frequency drive properly. The compatibility of the motor and vfd depends on

i'm new to pcb design and i'm wondering that starting from which frequency range we need to apply the high speed PCB design rules and techniques ?

I think it is normally from 4.0 to 5.0

Hi all I am facing the problem with reoworking CSP component for high frequency application boards. Our customer do not allow us to use tacky fluxes due to high frequency application and component has low standoff ,and the ball pad and ball size is

Hi all How can I find the technical paper or source of information about using No-clean flux with high frequency apllication. High frequency mean more than 2 GHz - 5 GHz. I heard from my colleague that No-clean flux residue on board effect to high

Hi there, in my factory we use profiling every temp. change or once per day others make 1 profile for machine per week what is safe in your oppinion to be sure that all products made are good :) or if 1 per week is enough how to prove it to bosses

Good afternoon, We develop reflow profile ones and control it daily or when recipe changes after that. Modern reflow ovens are usually very stable. This means that your zone temperature set points won�t deviate from initial ones. You can calculate d
