Pioneer in Custom-manufactured Paper Dummy Frame
Pen-Mei Technology Sdn Bhd was established in November 1993 as a distributor of paper lead frames and machinery automation parts such as bearings and shafts. By 1995, the Company has developed our own exclusive customisable paper dummy frame for mold cleaning purposes.
Paper lead frame is a unique product specially designed to substitute conventional metal lead frame or substrate for cost-reduction in mold cleaning process.
It is intentionally developed for mold cleaning, conditioning and dummy molding, usually for molds that are used in transfer encapsulating of electric and electronic components by means of epoxy molding compounds.
Customisable paper lead frames
Does not require change
for molding temperature and parameters
Specialise Cleaning Design
increases cleaning effectiveness in hard-to-reach areas
Non-corrosive
and thus safe to use
Costing Considerations
When placing orders for your custom-manufactured paper dummy frames, keep in mind these considerations when it comes to cost-budgeting:
Material Properties
| Paper Type | What type of paper do you need? Thick, thin, or laminated? |
| Frame Dimension | What is the size of the paper frame? |
| Paper Thickness | How many layers will the paper frame be? |
| Unit per Frame | How complex is the frame? |
| Process | How much labour and time is needed to complete the job? |
| Tooling Cost | What tool is required, ie. Hard tool or soft tool? |
Tools
Soft Tool vs Hard Tool
| Soft Tool | Hard Tool |
| Lower cost (amortised to per strip) | High cost (amortised to first 30kstps) |
| Higher cost per strip | Lower cost in the long run |
| For low volume production (few 100s) | For high volume production (few 1000s) |
| Involves more processes (3 or 4) | Less processes |
| Longer lead time (due to the process) | Shorter lead time (after initial set-up) |
| More burr (due to manual process) | Minimum burr with higher accuracy |
Design Requirements
When customising paper frames, we require the following materials and samples:
Minimum Design Requirements
Lead Frame Drawing & Thickness
Position of guide pin holes for loader and mold
Optional Design Requirements
Mold chase drawing or imprint (for multiple strips type)
