PCB Assembly Frame SMT Stencil Laser Cut 300mm*400mm for PCBA
Linked Electronics has the capability to manufacture pcb from single sided boards up to 32 layer multilayers ,and provide one stop turnkey services, including pcb manufacture, assembly, components source and function testing. The superior service we offer tp our customers is the key to our success and our mission has remained the same since 1998. And our commitment is to surpass customer's satisfaction all the time.
Linked offers nano coating on select stencils and sizes! "Nano coating” is a two part, wipe on process, made up of hydrophobic elements that repel flux and solder, resulting in improved paste release for extremely small components. If you have fine pitch QFN’s, fine pitch IC’s, micro BGA’s, and 0201 component types on your designed PCB or PCBA boards, nano coating stencil must be the best option for you, but the price will be more expensive than standard stencil
Linked One Stop PCB Service
1. PCB manufacturing
2. Components Souring

Look forward to your RFQs and hope we can work together.
Stencil Thickness Advise by Linked Electronics
QFP pitch ≤ 0.5mm, the sheet thickness choice could be either
0.13mm or 0.12mm;
If the pitch> 0.5mm, the stencil thickness can be between
0.15mm - 0.20mm;
If the BGA ball pitch > 1.0mm, 0.15mm thickness stencil is
a good option
If the 0.5mm≤BGA ball pitch ≤1.0mm, choose 0.13mm thickness for
your SMT work.
You can order one stencil with your PCB order at Linked Electronics. We have different thickness
and different size stencil showing below
