In my experience with flex the flex provider is the best place to go for these pallets. The competent flex and rigid flex providers will also provide the carriers if requested. Once you see what they are providing you, you could most probably make th

I agree, you will likely need a carrier being that thin. without seeing the trace layout I’m not sure about relieving the carrier to accommodate them. if evenly distributed you shouldn’t to go that far. Are parts on both sides of the board? Don’t mak

What equipment do you have? As well as the comments from others, another major influencing factor can be the residual heat in your PCB carrier. It takes more heat energy to warm a cold carrier than if it is already hot from the last cycle run. This

Generally, that should not be a problem. Software for this purpose is pretty simple, the main issue is how accurately pcb carrier will be positioned at both ends. This is purely dependent on printer's mechanics. I have an old DEK247 and thought about

I did a test where the leds were put into a 95% humidity at 60 degC environment for an hour, and after that almost all leds would stick into the carrier tape. So, moisture might certainly play a major role in the stickiness of the leds. We placed al

Hi Experts, I have noted a savings opportunity on our work-place as chipmounters discard carrier tapes which are easily separated in different waste-containers below the feeders. Normally the company pays a service to dispose that waste. Have anyon

Flexible circuits assembly is different from rigid board assembly. For some manfacturers, fpc assembly are some things more painful because the assembly quality is unstable. Recommend to check and hope these 2 blogs are helpful. Flexible Circuit Asse

Thank you for your reply! I will see how it goes without the carrier pallets. I was worried about them drooping too far in the center (at the center V-Score) and falling off of the conveyor in the reflow oven. I am putting boarders on all sides of
