Your paste should specify a number of times it is OK for various things to happen. The two you might care about are the "Stencil Time"/"Working life", which is how long the paste can be out of the pot on your stencil while you print PCBs. The othe

I' designing a PCB with SMD components to optimize the land patterns for wave soldering. I find that the IPC-SM-782 land patterns are not robust enough for wave soldering, yielding ramdom skips and bridges. This PCB will also give me insight on sha

Hi everbody, I'm facing some soldering problems with a Diode (SMA) during wave soldering process. During this process almost all the time one of the component pads have no solder, according to the picture dsc000604 attached. Some considerations: * T

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

Hi all, I mean after post adhesive oven curing (SMD at bottom side) prior to manual insert of PTH components (top side), what is the recommended storage time prior to wave soldering in order to avoid pin/blow holes and sunken joints issues (pcb asse

Hello everyone, I have a question regarding wavesoldering and measuring if a proces/machine is in control. I made a custom carrier for measuring contact time, parallelism, solder temperature, coveyorspeed and some data of the preheat section. The s

| Currently, we are baking any PCB before process on SMT, the 'reason' is to dry any possible humidity that could be inner the PCB, it does not matter if the PCB is multilayer or not. We bake PCB's at 107C for 4 hrs and the board must be process into

Necoleta, PWB Blistering/De-lamination may not be due for Titanium finished threads / holders which is typically being used to draw high Shelf Life of Pallets and even flow across Auto Wave Soldering rails. There is also nothing to suspect on Liquid
