If the parts are hand placed and hand trimmed, why do you need to inspect whether the lead is in the hole. The operator should be inserting the part correctly. We have MIRTEC machines and they do a pixel comparison to "known good images". With a m

We recently had a multi block panal change at the vendor Now the production lines are producing solderability defects in great number. The makeup of the pcb is a type of fiber glass mask green in color and pads with no tinning just copper lands.

Hi Luis A white mask typically helps in the marking process since you are not reliant upon the PCB layers to create the contrast. Laser marking is really an etching process, so if your laser is set properly (power and focus) the goal with mask is to

We only use it for resistor color code and most other comps it just checks for presence. No solder joints.

The critical operations where cross contamination can occur is the paste printer, the touch up station and the hand soldering station. Hand insertion should not be a problem if the parts are kitted or issued with proper control. If possible I would

Hi Pavel, Real Chunks, Thanks for your valuable inputs..Selecting the correct location for board profiling is critical in determining the solder joint quality. Am I right to say TC wire attachment locations priority should be as below: (1) Thermal

Hi all, Is there anyone know the correct way to obtain the accurate temperature profiling for oven reflow? Are below claims true? (1) Instead of full components on the PCBA (Motherboard), the profile taken from PCBA with few components can be cons

Does anyone have an ESE LX3 printer installed and running at their facility? I'm curious if you've had any problems, or major break-downs. I'm wondering in your experience how it handles different color solder mask. Any issues you found with the squ
