A common bottomside heater configuration is IR-Convection-Convection. One of the big advantages of the IR zone is its ability to allow the flux carrier to spread and dry slowly before the board reaches the convections zones, which can blow wet flux c

Hi all, Need advice how to fix RJ45 short issue after wave solder m/c .Few actions taken to resolve this issue but the outcome was inclusive which was 1. Modify wave pallet 2. Change conveyor setting from 0.8meter/minute to 0.7 meter/minute 3. Clear

Hi all, * Defect : termial to terminal touching btw two melfs body that created short circuit. * Clearance : 0.8mm btw two melfs body. * Size melf : diameter=2.4mm to 2.7mm, length=4.8mm to 5.2mm * Stencil opening : "v" shaped to minimise component

we have two similar pcb from two different pcb manufacturer one of them passed the wave soldering without any short circuit and residue and another one passed it with many residue . don`t you think that the type of solder mask from these two pcb manu

We have a problem with soldering of a 96 pin header connector(9001-11961c00l1a from kingmate) we use 3 different wave soldering but in all of the machines we have many short circuit between the pins . the wave soldering machines that we use is fr

we have problem in setting the density of a no clean flux for using before wave soldering . first we dilute the flux but we have many short circuit problem between the pads of edge connector,then we densify the flux all the short circuit is removed b

orientation is also a factor here, So what is the pitch of these connectors? the lead length? the hole dimensions? surface finish? and what type of wave and flux are you running? Shorts are pretty easy to eliminate if everything is of adequate des

If you have surface mount on the bottom, you can place openings between any thru-hole parts that constantly short. Your adhesive is a natural solder block!

I think so. My customer once assembled resistors 0402 ,by Glue+wave soldering process. But PCB must be printed soldermask bridge between 0402 SMD PADs, otherwise you would encounter short problem. Sorry I don't have any comment for recommended footp

Hi Joris - There is an excellent wave solder guide called "Take No Prisoners" that includes instructions for attacking and eliminating solder balls and preventing their recurrence: 1. Increase Dwell Time Solder balls are normally caused by too much f
