How can I electrically isolate a PCB from a heat sink?

I have a set of LED driving lights for motorcycle that must be wired through a ground-leg pulse width modulation dimmer. The problem is the mounting bracket for the lights is grounded, so the lamp shorts to ground through the motorcycle chassis and the PWM dimmer cant dim the lamps. How do I handle this problem?

Use Kapton tape
Use Sil-pad and shoulder washer. If you use a sil-pad the screw will still electrically connect the componet tab with the heat sink, soashoulder washer should be used to isolate the screw and the tab.

Como posso separar a antena PCB e o conector SMA?

I am designing a prototype PCB for a Lora node. It will have an SMA connector (J2) and a PCB antenna. Switching RF connectors are not available in my area, so as an amateur enthusiast what is a good way to separate the antennas?

Como você monta componentes eletrônicos no chassi de um veículo com segurança?

I want to implement a control system I designed for a light electric motorbike. I would like to mount it as professionally as possible on the chassis. It consists of a power system pcb and a SAMC21 development board which I’ll merge later once this all works properly. I have tried screwing it directly on the aluminium chassis but have found that shocks and vibrations from the horn disturbed the system or even destroyed it upon large shocks. Is there a specific way car and motorcycle manufacturers mount their electronics to make their system as robust as possible?

Can we do wave solder the through hole parts without masking it?

We would like to do wave soldering for the through hole components. All through hole components are top side of PCB. Only test points, which require mask during process, are on the bottom side. So there is a extra labour cost at adding and removing the mask. Can we do wave solder the through hole parts without masking it?
