Hi All, Anybody knows what is the minimum clearance between through hole component and chip component? Problem description: On bottom side of my pcb are only 0603 chip components mounted on glue. One of the component is located very close to hole

Very smart, Chunks.

Reflow => Top side DIP => Bottom side glue => Bottom side SMT => Wave solder ... We couldn't keep the DIP clinch apparatus away from the bottom side SMT if we did the bottom side SMT prior to DIP.

Marcin, Think outside the box. If you are glueing the SMT part down, why not have an aperture cut in your stencil (or recut a stencil) between the SMT part and thru-hole. Wave solder hates SMT glue. This will get rid of your solder short problem

I would like to ask after glue bonding is abalibity drop. I test by force equipment that it is very difficult to drop after reflow 2. Very due by DIP machine. I check after Dip many chip drop. I wonder the glue not qualify I am using IR 130. Could yo

We'll guarantee the two pads are too close together. The proper spacing depends on the orientation of the parts to the wave. * Do the pads hit the wave at the same time? * Does one pad hit the wave before the other? If so, which? * How does the 06

Hi, The distance between the two terminations/endings/pads of 0603 (0201)is 0.15mm i.e. lesser than than the distance between the 0603 and through hole i.e. 0.5mm My ques is that, then why its termination doesnot short as it has a minimum distance.A

Hi everybody, The matter is this: after reflow, on top side leads of chip components (resistor 0805)appear some empty balls of solder. In some cases this thing is only on the lead and the solder joint seems good, in other cases this empty ball is als

I think you answered your own question. Try a different lot or mfger of this part. You can prolly get a sample sent over nite and hand place them to verify. Trying to find out why these resistors "explode" when touched with a needle is like findin
