STHL PCBA workers operates carefully and uses professional device to avoid such damage in the past years. All of our PCB boards move from one process to next process with the PCB SMT storage carts. We use PCB storage cart with many advantage.

1) Provides safety and convenience

2) Durable mobile unit

3) Adjustable panels with horizontal slides features 15mm spacing for high-density loading

4) Ideal for transporting work process and storing large quantities of PCB

5) Stainless steel panel allow for airflow and conductivity, and have slides that accept different thickness PCB boards.


What information needed for PCBA quotation?

Whenever you have new PCBA projects need to estimate cost, or old projects just for price comparing, please send us your files, we will email you a quote within 24 hours. Basic files for price estimate just need a BOM list with clear components details.

Files needed for PCB Assembly quotation and PCBA production.

  1. Bill of materials or BOM  (better in Excel format) 2.     PCB Gerber files
  2.    Pick and place file or XYRS data file

1) The BOM list needs to show information of Value, Quantity, Description, Footprint, Designator


2)  PCB Gerber files (if no files yet, can offer details of layers, size, thickness, copper weight and surface finish)


3)  Pick and place file (This file allows us to finish a quick and perfect placement of SMT process.)
