Hi,
I have been using the HA7210 crystal oscillator for a number of years across a whole host of products. Its a simple IC with a crystal on the input giving a clock signal on the output. However I have received several batches lately made in different countries all of which have a failure...
Hi,
I am looking for a fairly quick setting, low temp cure potting compound or epoxy/adhesive that is self levelling/low viscosity. It will be used to fill fairly wide/long (only 1 -2mm deep) voids in a PCB. It also needs to be non-conductive. It doesn't have to set hard, so can be rubbery...
Hi,
Does anyone know what the surface mount alternative is to a BAT46 small signal Schottky diode. I can only seem to get them as a DO35 package (leaded). I am assuming the surface mount alternative has a different number?
Thanks
Hi,
I need some help/advice on the best way to solder or epoxy a gold packaged device onto a gold plated track. At present we use an Indium solder, however it is very time consuming as the substate tracking has to be pre-tinned and each individual component is pre-tinned before the packages...
Please can someone advise on the best epoxy to use for pressure sealing?
I am trying to seal a cavity on top of an RF filter which contains the tuning screws. The unit is pressurised to 3.5bar and the leak rate has to be better that 5cc/hr.
We have tried eccobond type epoxies, but after aging...
Please could someone point me in the right direction....?
A little while ago I used to have an A4 sheet which gave different screw head types and the basic dimensions. It also gave the dimensions for nuts and spring washers etc.
However as happens to all useful bits of paper it got...
Hi there,
I am currently having a problem with a Sample and Hold circuit that is used to Sample a voltage which can range from 3V down to 2mV. The output of this is then fed to a comparator which compares the sample and hold value with the next signal received. This then either gives an...
Hi,
Hopefully someone will be able to help me.....
I need to test and select a batch of SOIC 16pin IC's on the PEC that its used on to determine which IC's will and which won't work. Its all to do with the interaction of the IC and the surrounding components!
Basically I am looking for a...
